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  - Organochlorine pesticide - lindane, according to the US EPA classification, is considered
as potentially carcinogenic compound. Although the usage of this pesticide is banned in
many countries, it is still used in some. As persistent organic compound, lindane and its
residues can persist in the environment for a very long time, migrating over long distances,
potentially causing environmental pollution. Lindane residues can reach the human body
through the food chain, because this potentially toxic compound is prone to
bioaccumulation, and this is serious toxicological problem especially at industrial and
agricultural sites where lindane has been used directly, or has reached due to improper
wastewater disposal. Despite bans on its use, lindane contamination remains a global
problem, and its removal from the environment is of crucial importance. In this research,

glycidyl methacrylate was utilized, which proved to be a very effective sorbent, with
lindane sorption of about 80 %. Analytical technique, Gas Chromatography with an
Electron Capture Detector (GC-ECD), was used for determination of lindane

performed using different solvents, which confirmed the possibility of recycling and reuse
of the investigated polymer.

AB  - Cross-linked macroporous copolymers based on glycidyl methacrylate (GMA) have
been used as sorbents for metals, support for enzymes, as biomaterials etc. In this
research GMA copolymer was prepared by copolymerization of GMA (glycidyl
methacrylate) and EGDMA (ethylene glycol dimethacrylate), in the presence of inert
component (90 mass% of cyclohexanol and 10 mass% of dodecanol), and functionalized
with diethylenetriamine (DETA). Presence of epoxy groups in GMA-based copolymers
allows chemical modifications on the polymer in order to achieve its different
applications. GMA-based copolymer was activated with 0.1 M solution of Ga(NO3)3, at
pH 3, and 25 °C [1].
Antimicrobial activity of functionalized and activated GMA-based copolymer,
GMA/Ga, was analyzed against Staphylococcus aureus (Gram positive bacteria),
Escherichia coli (Gram negative bacteria), Candida albicans (yeast) and Aspergillus
niger (fungi) [2]. The agar-well diffusion method was used to evaluate antimicrobial
activity of GMA/Ga polymer. Nutrient agar plates were inoculated with broth of 1 MFU
microbial suspensions. Wells of 5 mm diameter were punched in the inoculated plates
using a sterile metallic borer, and then filled with 100 μL of water solution containing
nanoparticles of GMA/Ga copolymer, at various concentrations: 10, 20, and 30 mg/mL.
Control wells were filled with 100 μL of distilled water. Inoculated plates were incubated
at 37 °C/24 h for bacteria and yeast, and at 30 °C/48 h for fungus. Antimicrobial activity
of Ga activated copolymer was evaluated by measuring the inhibition zone diameter
around the wells. The GMA/Ga copolymer displayed good antimicrobial activity against
Escherichia coli and Candida albicans, which makes it selective for Gram negative
bacteria and yeasts, and as a material that can be potentially used for biomedical
applications, in food industry etc.
