AB  - Two series of polyurethane (PU) composites based on poly(ε-caprolactone), aliphatic
hyperbranched polyester, isophorone diisocyanate and different content (0.5, 1 and 2 wt.%) of
unmodified or surface-modified TiO2 nanoparticles were prepared. For the surface modification
of TiO2 nanoparticles lauryl gallate was applied. Neat PU and composites were prepared by a
two-step solution polymerization method, using sonification in an ultrasonic bath for composite
fabrication in order to achieve homogenous distribution of nanoparticles, added in the first step of
polymerization reaction. Morphology of prepared neat PU and its composites were investigated
by utilizing scanning electron microscopy (SEM) and atomic force microscopy (AFM).
According to the obtained SEM micrographs, neat PU has compact and uniform cross-sectional
morphology, while in the structure of its composites small voids and certain micro-structures,
such as clusters or aggregates, can be observed. Furthermore, SEM-EDS measurements
confirmed the presence of Ti atoms in composites, originating from the incorporated nanoparticles. AFM analysis showed the existence of microphase separated morphology on the
surface of PU and its composites. Moreover, the surface of both series of composites became
rougher with the addition of nanoparticles, and its roughness increases with increasing amount of
TiO2 nanoparticles. Prepared PU composites may have potential application as coatings.

AB  - Polyurethane networks (PUNs) are versatile materials that have a wide range of
applications. Their structure is often segmented which means that it is built from thermodynamically incompatible flexible soft (SS) and rigid hard segments (HS) leading to the formation of microphase separation in the PUNs. With the careful design and selection of SS and HS it’s possible to control PUNs structure, morphology, solvent resistance, etc. Here, polycaprolactone (PCL) was used as SS to prepare segmented PUNs, due to its attractive features, such as low glass transition temperature (around -60 °C), biocompatibility, biodegradability, hydrophobicity, good solubility in various solvents, high permeability to many gasses, etc., in order to prepare PUNs with desired surface properties for their application as coatings [1,2].
In this study, a series of PUNs was synthesized by a two-step polymerization process, according to the procedure described elsewhere [1,3]. The synthesized PUNs are based on Boltorn®
hydroxy-functional aliphatic hyperbranched polyester of the second pseudo generation (BH-20,
Mn = 1340 g mol-1), isophorone diisocyanate (IPDI) and polycaprolactone diol (PCL, Mn
 = 2000 g mol-1). Five samples with diferent SS content (from 10 to 50 wt.% SS content) and constant –NCO/−OH molar ratio of 1.05 were synthesized. Stannous octoate (Sn(Oct)2
) was used as a catalyst, while a mixture of N,N-dimethylacetamide (DMAc) and tetrahydrofuran (THF) was used as a solvents during the synthesis of PUNs. PUN samples were labeled as PUN-XX, where XX represents the SS content (from 10 to 50). Surface morphology and the surface roughness of the PUNs were investigated by atomic force microscopy (AFM). AFM examination of
PUNs was performed by applying NTEGRA Prima atomic force microscope (NT-MDT, Moscow, Russia). Measurements were done using NT-MDT NSGO1 silicon cantilevers (N-type,
antimony doped with Au reflective coating). The nominal force constant of the cantilevers was
5.1 N m-1, whereas the cantilever driving frequency was around 150 kHz. Intermittent-contact
AFM mode was applied and data related with topography and phase were collected. AFM
images were created and analyzed with Image Analysis 2.2.0 (NT-MDT) and Gwyddion 2.61
(Free and Open Source software, Czech Metrology Institute) software. The scan area of the
PUNs surface was 20 × 20 μm2.
AFM analysis was carried out to explore the surface topography, homogeneity and the
impact of the SS content on microstructural features of the synthesized PUNs, such as nanometer scale structures and roughness. The recorded 3D height and 2D phase pictures (scan size 20
× 20 μm2) and obtained roughness values are presented in Figure 1 and Table 1, respectively.
According to the captured 3D height pictures it can be seen that surface topography of PUNs
strongly depends on the SS content. That is reflected in the fact that samples with smaller SS
content have more flat and smoother relief structures, without any larger domains, opposite
to the samples with the higher SS content. Furthermore, according to the presented 2D phase
pictures it can be observed that prepared PUNs have heterogeneous surface morphology, due to
the existence of more pronounced and more noticeable interface borders between phases. This
behavior is more prevalent in PUN samples with higher SS content [3]. The examined roughness of the PUNs shows that samples with SS content of 30 and 40 wt.% (PUN-30 and PUN-40
samples) have the highest roughness values (Rq and Ra, Table 1). The reason for this may lie in the fact that these samples have optimal ratio between HS and SS, allowing easier organization of SS [4].
A series of PUNs based on BH-20, IPDI and PCL was successfully synthesized. AFM
analysis showed that the content of SS has a significant impact on the surface properties of
these PUNs. Moreover, PUNs have two phase morphology that originates from the presence of
HS and SS, and it was more pronounced in the samples with higher SS content [5].

AB  - Nanoemulsions (NEs) are frequently used in the food, cosmetics and pharmaceutical industries to deliver nutraceuticals, pharmaceutical or cosmetic active ingredients. When administering NEs parenterally, various stabilisers are added to prevent rapid plasma clearance and to successfully deliver the active ingredient to the target site. For this purpose, PEGylation is often used to prolong the circulation time of the droplets. However, the problem is to determine the optimal concentration of the PEGylating agent – the PEGylation efficacy – that ensures adequate surface protection. This is a particular challenge when the active ingredient is incorporated into the stabilising layer, where any changes could disrupt the stability of the droplet. For this reason, we aimed to determine the optimal concentration of PEG2000-DSPE for surface protection of curcumin-loaded NEs for parenteral administration using electron paramagnetic resonance (EPR) spectroscopy. NEs were prepared using the high pressure homogenisation technique with 0.1 %, 0.3 % or 0.6 % of the PEGylated phospholipid. A droplet size of approximately 100 nm and polydispersity index below 0.25 indicated suitability for parenteral application. EPR analysis showed that PEG2000-DSPE had a stabilising effect on selected NEs, which was most pronounced in the part of the stabilising layer closest to the aqueous phase. To confirm these results, protein interaction studies were carried out using dynamic light scattering, UV–Vis spectroscopy, atomic force microscopy and release studies from protein-enriched media – bovine serum albumin (BSA) or foetal bovine serum (FBS) in phosphate-buffered saline. These analyses confirmed that the addition of PEG2000-DSPE reduced protein binding to the droplets as a function of concentration, with 0.3 % providing the best protection for the droplets. Our conclusions from the EPR spectroscopy study demonstrate the usefulness of EPR in determining the optimal concentrations of PEGylating agents for surface coverage and its usefulness in the formulation development phase.

AB  - Preclinical development of deuterated pyrazoloquinolinone ligands, promising drug candidates for various neuropsychiatric disorders, was hindered by unusually low solubility in water and oils. DK-I-60-3 (7-methoxy-d3-2-(4-methoxy-d3-phenyl)-2,5-dihydro-3Hpyrazolo[4,3-c]quinolin-3-one) is one of such pyrazoloquinolinones, and we recently reported about increased oral bioavailability of its nanocrystal formulation (NC). Lipid nanoparticles (LNP) with a high concentration of lecithin, which enhances loading capacity of the lipid matrix, may give rise to further improvement. After preformulation studies by differential scanning calorimetry and polarized light microscopy, LNP were prepared by the hot high pressure homogenization, and characterized in terms of particle size, morphology, and encapsulation efficacy. The layered structure visible on atomic force micrographs was confirmed by nuclear magnetic resonance. Obtained formulations were desirably stable, with small particle size (<100 nm), and high encapsulation efficacy (>99 %). Lecithin was partially fluid and most probably located in the outer shell of the particle, together with DK-I-60-3. While the hydrophobic part of polysorbate 80 was completely immobilized, its hydrophilic part was free in the aqueous phase. In oral neuropharmacokinetic study in rats, an around 1.5-fold increase of area under the curve with LNP compared to NC was noticed both in brain and plasma. In bioavailability study, F value of LNP (34.7 ± 12.4 %) was 1.4-fold higher than of NC (24.5 ± 7.8 %); however, this difference did not reach statistical significance. Therefore, employment of LNP platform in preclinical formulation of DK-I-60-3 imparted an incremental improvement of its physicochemical as well as pharmacokinetic behavior.

AB  - Electrophotography is affected by several parameters, including printing machines and paper type, which determine the final quality of reproduction. For the
investigation of those effects, tests were done on the three types of electrophotography printing machines and eight types of uncoated paper with different properties of
weight, surface roughness, whiteness, brightness and opacity. Samples were printed with cyan, magenta, yellow and black toner under the standard, identical conditions.
The assessment of standard print quality parameter (optical density) was done using spectrodensitometer Techkon Spectro Dens. At the same time, the paper substrates
were characterized using the atomic force microscopy (AFM) as well as by spectrophotometric measurements (X Rite Eye-One, i1). Obtained results showed that the
reproducibility significantly depends on the type of printing machine rather than optical and mechanical properties of paper.

AB  - Macroporous (glycidyl methacrylate) GMA-based composite was
synthesized via suspension polymerization in the presence of 2 wt. % magnetic
nanoparticles and functionalized with triethylenetetramine. Copper was immobilized
on composite by contacting modified copolymer with 0.1 M solution of CuCl2, at pH
5, and 25 ̊C. The obtained composite was characterized by mercury porosimetry,
Fourier transform infrared spectroscopy (FTIR) analysis and atomic force
microscopy (AFM). GMA-based composites, due to their properties (size, porosity,
etc.), and the presence of reactive epoxy group, have found a variety of applications
as sorbents, enzyme supports, in biomedical applications, for metal and organic
compounds sorption.1
The antimicrobial activity of the synthesized GMA/Cu copolymer against
Staphylococcus aureus, Escherichia coli, Candida albicans and Aspergillus niger as
representatives for Gram-positive bacteria, Gram-negative bacteria, yeast and fungi
were investigated in this study.2 The copolymer displayed good antimicrobial activity
against all analyzed microbes, which makes it a material that can be potentially used
for biomedical (antibacterial and antifungal) applications.

AB  - The aim of this work was to examine the influence of polycaprolactone (PCL) as a soft segment (SS) on the surface properties of polyurethane networks (PUNs). Five PUNs with different SS content (from 10 to 50 wt%) were prepared using Boltorn® aliphatic hyperbranched polyester of the second pseudo generation and isophorone diisocyanate as components of hard segments. The structure, hydrophobicity, wettability, and swelling behavior of these PUNs were investigated. Primarily, the obtained results showed that properties of prepared PUNs strongly depend on the content of SS that is, PCL. It has been established that the increase of SS content reduced the degree of hydrogen bonding in PUNs. Also, the increase of the SS content in PUNs induced appearance of more pronounced microphase separated morphology, better hydrophobicity and non-wetting with diiodomethane. Simultaneously, the increase of the SS content led to the decrease of contact angles with formamide, and surface free energy of the prepared PUNs. These PUNs show good surface properties that are required for their potential application such as coatings.

AB  - Polymeric film-forming systems have emerged as an esthetically acceptable option for targeted, less frequent and controlled dermal drug delivery. However, their dynamic nature (rapid evaporation of solvents leading to the formation of thin films) presents a true characterization chal- lenge. In this study, we tested a tiered characterization approach, leading to more efficient definition of the quality target product profiles of film-forming systems. After assessing a number of physico- chemico-mechanical properties, thermal, spectroscopic and microscopic techniques were introduced. Final confirmation of betamethasone dipropionate-loaded FFS biopharmaceutical properties was sought via an in vitro skin permeation study. A number of applied characterization methods showed complementarity. The sample based on a combination of hydrophobic Eudragit® RS PO and hy- droxypropyl cellulose showed higher viscosity (47.17 ± 3.06 mPa·s) and film thickness, resulting in sustained skin permeation (permeation rate of 0.348 ± 0.157 ng/cm2 h), and even the pH of the sample with Eudragit® NE 30D, along with higher surface roughness and thermal analysis, implied its immediate delivery through the epidermal membrane. Therefore, this study revealed the utility of several methods able to refine the number of needed tests within the final product profile.

AB  - The problem of wastewater has long been ubiquitous and has great consequences for the environment and its
inhabitants. Microbial fuel cells (MFCs) have enormous potential for the treatment of wastewaters polluted with
azo dyes. The amount of energy that can be produced from a single-chamber MFC is sufficient to perform
decolorization and degradation of such dyes, which are widely used in the textile industry. This study on the azo
dye, reactive black 5 (RB5), provides an alternative method through three parallel-connected MFCs to obtain
electricity that directly serves for the dye’s electrochemical degradation. We examined degradation followed by
decolorization of RB5 using Fe and Pt electrodes, together with H2O2, to achieve the electro-Fenton process. The
amount of voltage produced (295 mV), the current density (276 mA m− 3
) and the power density (50 mW m− 3
)
were sufficient to degrade 25 mg L-1 RB5 dye with 0.5 mM H2O2 in just 2 h. The dye degradation mechanism was
investigated using UV–VIS, FT-IR and HPLC-MS/MS. The ecotoxicity of the degradation products was assessed
using a bacterial model, Aliivibrio fischeri. These tests showed that there was successful degradation of the dye to
products whose toxicity is less than that of RB5.

AB  - A nanotechnology-based approach to drug delivery presents one of the biggest trends in biomedical science that can provide increased active concentration, bioavailability, and safety compared to conventional drug-delivery systems. Nanoemulsions stand out amongst other nanocarriers for being biodegradable, biocompatible, and relatively easy to manufacture. For improved drug-delivery properties, longer circulation for the nanoemulsion droplets should be provided, to allow the active to reach the target site. One of the strategies used for this purpose is PEGylation. The aim of this research was assessing the impact of the oil phase selection, soybean or fish oil mixtures with medium chain triglycerides, on the physicochemical characteristics and injectability of curcumin-loaded PEGylated nanoemulsions. Electron paramagnetic resonance spectroscopy demonstrated the structural impact of the oil phase on the stabilizing layer of nanoemulsions, with a more pronounced stabilizing effect of curcumin observed in the fish oil nanoemulsion compared to the soybean oil one. The design of the experiment study, employed to simultaneously assess the impact of the oil phase, different PEGylated phospholipids and their concentrations, as well as the presence of curcumin, showed that not only the investigated factors alone, but also their interactions, had a significant influence on the critical quality attributes of the PEGylated nanoemulsions. Detailed physicochemical characterization of the NEs found all formulations were appropriate for parenteral administration and remained stable during two years of storage, with the preserved antioxidant activity demonstrated by DPPH and FRAP assays. In vitro release studies showed a more pronounced release of curcumin from the fish oil NEs compared to that from the soybean oil ones. The innovative in vitro injectability assessment, designed to mimic intravenous application, proved that all formulations tested in selected experimental setting could be employed in prospective in vivo studies. Overall, the current study shows the importance of oil phase selection when formulating PEGylated nanoemulsions.

AB  - Aims Because the Staphylococcus aureus is one of the most well‐known pathogens associated with medical devices and nosocomial infections, the aim of the study was to examine antibiofilm potential of emodin against it.  Methods and Results Antibacterial activity was examined through microdilution assay. Antibiofilm testing included crystal violet staining of biofilm biomass and morphology analysis by Atomic force microscopy (AFM). Furthermore, aerobic respiration was monitored using the Micro‐Oxymax respirometer. For investigation of gene expression qRT‐PCR was performed. Emodin demonstrated strong antibacterial activity and ability to inhibit biofilm formation of all tested strains. The effect on preformed biofilms was spotted in few strains. AFM revealed that emodin affects biofilm structure and roughness. Monitoring of respiration under emodin treatment in planktonic and biofilm form revealed that emodin influenced aerobic respiration. Moreover, qRT‐PCR showed that emodin modulates expression of icaA, icaD, srrA and srrB genes, as well as RNAIII, and that this activity was strain‐specific.  Conclusion The results obtained in this study indicate the novel antibiofilm activity of emodin and its multiple pathways of action.  Significance and Impact of Study This is the first study that examined pathways through which emodin expressed its antibiofilm activity

AB  - Food packaging ensures safety and hygiene, while reducing food waste, therefore it is and ssential component of the food supply chain. A sustainable and biodegradable alternative to conventional food packaging is edible packaging which contributes to the reducing waste and the economic efficiency of packaging materials. The numerous biopolymeric materials could be used as source such as polysaccharides (starch, cellulose, chitosan) and proteins (gelatin, soy protein, whey). Exopolysaccharides (EPS) are fermentation-based biopolyrners, secreted outside the cell wall and synthesized by various microbial species including bacteria, fungi and blue-green algae. Microbial levan is fructose-based EPS and convenient due to its biocornpatibility, renewability, high molecular weight, low viscous nature, antioxidant and prebiotic effects. Levan used in this work was produced by the B. licheniformis NS032 strain and its hydrophobic derivatives were obtained using octenyl succinic anhydride (OSA). Degree of substitution (DS) for modified levans were 0.025 and 0.032 for LH22 and LH25 respectively. Three different film compositions were prepared: 
levan/LH22/LH26 with gelatin in proportions 1:1. Films were prepared by casting technique and evaporated at room temperature. Morphology of the obtained films were studied by ARV (Atomic force microscopy), AutoProbe CP-Research SPM (TM Microscopes-Broker) and mechanical properties were examined by Shimodzu E2-LX tensile tester. The samples had thickness of 150 trrrl. Based on morphological measurements, it can be concluded that use of levan derivatives change roughness of the levan/gelatin blend film. The best mechanical properties (tensile strength and elongation at break) were obtained with pure levan. Obtained films are composed from edible and biodegradable components and therefore are potentially applicable in food industry. Future investigation will be focused on optimization of levan/gelatin proportion and more extensive 
structural and mechanical properties of obtained films.

The samples had thickness of 150 trrrl. Based on morphological measurements, it can be concluded that use of levan derivatives change roughness of the levan/gelatin blend film. The best mechanical properties (tensile strength and elongation at break) were obtained with pure levan. Obtained films are composed from edible and biodegradable components and therefore are potentially applicable in food industry. Future investigation will be focused on optimization of levan/gelatin proportion and more extensive 
structural and mechanical properties of obtained films.",

AB  - Poor water solubility of new chemical entities is considered as one of the main obstacles in drug development, as it usually leads to low bioavailability after administration. To overcome these problems, the selection of the appropriate formulation technology needs to be based on the physicochemical properties of the drug and introduced in the early stages of drug research. One example of the new potential drug substance with poor solubility is DK-I-60-3, deuterated pyrazoloquinolinone, designed for the treatment of various neuropsychiatric disorders. In this research, based on preformulation studies, nanocrystal technology was chosen to improve the oral bioavailability of DK-I-60-3. Nanocrystal dispersions stabilized by sodium lauryl sulfate and polyvinylpyrrolidone were prepared by modified wet media milling technique, with the selection of appropriate process and formulation parameters. The nanoparticles characterization included particle size and zeta potential measurements, differential scanning calorimetry, X-ray powder diffraction, dissolution and solubility study, and in vivo pharmacokinetic experiments. Developed formulations had small uniform particle sizes and were stable for three months. Nanonization caused decreased crystallite size and induced crystal defects formation, as well as a DK-I-60-3 solubility increase. Furthermore, after oral administration of the developed formulations in rats, two to three-fold bioavailability enhancement was observed in plasma and investigated organs, including the brain.

AB  - The current study describes the experimental design guided development of PEGylated nanoemulsions as parenteral delivery systems for curcumin, a powerful antioxidant, as well as the evaluation of their physicochemical characteristics and antioxidant activity during the two years of storage. Experimental design setup helped development of nanoemulsion templates with critical quality attributes in line with parenteral application route. Curcumin-loaded nanoemulsions showed mean droplet size about 105 nm, polydispersity index <0.15, zeta potential of −40 mV, and acceptable osmolality of about 550 mOsm/kg. After two years of storage at room temperature, all formulations remained stable. Moreover, antioxidant activity remained intact, as demonstrated by DPPH (IC50 values 0.078–0.075 mg/mL after two years) and FRAPS assays. In vitro release testing proved that PEGylated phospholipids slowed down the curcumin release from nanoemulsions. The nanoemulsion carrier has been proven safe by the MTT test conducted with MRC-5 cell line, and effective on LS cell line. Results from the pharmacokinetic pilot study implied the PEGylated nanoemulsions improved plasma residence of curcumin 20 min after intravenous administration, compared to the non-PEGylated nanoemulsion (two-fold higher) or curcumin solution (three-fold higher). Overall, conclusion suggests that developed PEGylated nanoemulsions present an acceptable delivery system for parenteral administration of curcumin, being effective in preserving its stability and antioxidant capacity at the level highly comparable to the initial findings.

AB  - This paper presents an application of a portable microfluidic platform based on a filter paper on which multi-walled carbon nanotubes were deposited to quickly determine the quality of olive oil by measuring electrical resistance. Three different types of filter paper with different pore sizes and different filtration rates were used in the middle of the microfluidic platform, as a material for soaking a blend of olive and high-oleic sunflower oil. The rapid prototyping xurographic technique was used to fabricate the complete microfluidic platform. For testing purposes, oil blends in various proportions were deposited through the inlet on the top of the platform. The variation in electrical resistance at room temperature was measured, using the Chemical Impedance Analyzer, successfully indicating oil proportions in measured blends. We obtained the change of resistance in the range from 0.26 MΩ to 2.79 MΩ per percentage of olive oil content, for corresponding linearity index from 0.71 to 0.99, for papers labelled with 44–45, respectively. Additionally, a prototype of electronic device was developed for acquisition and displaying measured data, based on the created microfluidic platform.
