AB  - Vitamin K refers to a group of vitamins that play an important role in blood coagulation and regulation of bone and vascular metabolism. However, vitamin K3 may give severe side effects in animal and humans when improperly added to food and feed due to its toxicity. Here, an electrochemical biosensor, based on the YaiB NADPH-dependent quinone reductase from Lactococcus lactis (YaiB), was developed to achieve rapid and redox probe-free detection of vitamin K3. First, the ability of the carbon electrode to distinguish between 1,4-benzoquinone and hydroquinone was demonstrated. Then, we engineered YaiB to work as a bioreceptor immobilized at the electrode and its sensitivity and specificity to reduce vitamin K3 were demonstrated. Finally, to demonstrate the practical potential of the biosensor, we tested it directly in spiked milk samples, achieving 15-minute quantification of the vitamin K3. The limit of detection was 0.87 µM and 4.1 µM in buffer and milk, respectively.

AB  - Covalent organic frameworks (COFs) are emerging as promising sensing materials due to their controllable structure and function properties, as well as excellent physicochemical characteristics. Here, specific interactions between a triazine-based COF and a mass-used herbicide – glyphosate (GLY) have been utilized to design a disposable sensing platform for GLY detection. This herbicide has been extensively used for decades, however, its harmful environmental impact and toxicity to humans have been recently proven, conditioning the necessity for the strict control and monitoring of its use and its presence in soil, water, and food. Glyphosate is an organophosphorus compound, and its detection in complex matrices usually requires laborious pretreatment. Here, we developed a direct, miniaturized, robust, and green approach for disposable electrochemical sensing of glyphosate, utilizing COF's ability to selectively capture and concentrate negatively charged glyphosate molecules inside its nanopores. This process generates the concentration gradient of GLY, accelerating its diffusion towards the electrode surface. Simultaneously, specific COF-glyphosate binding catalyses the oxidative cleavage of the C–P bond and, together with pore nanoconfinement, enables sensitive glyphosate detection. Detailed sensing principles and selectiveness were scrutinized using DFT-based modelling. The proposed electrochemical method has a linear working range from 0.1 μM to 10 μM, a low limit of detection of 96 nM, and a limit of quantification of 320 nM. The elaborated sensing approach is viable for use in real sample matrices and tested for GLY determination in soil and water samples, without pretreatment, preparation, or purification. The results showed the practical usefulness of the sensor in the real sample analysis and suggested its suitability for possible out-of-laboratory sensing.

AB  - Nanocrystalline iron manganite powder was synthesized using the sol–gel combustion process, with
glycine as fuel. It was further calcined at 900  C for 8 h, resulting in the formation of a loose cubic
FeMnO3 powder with a small specific surface area, net-like structure and plate-like particles as
confirmed by XRD, N2 physisorption, FESEM and TEM analyses. The metal ion release was studied by
ICP-OES and showed that less than 10 ppb of Fe or Mn ions were released by leaching in water, but
0.36 ppm Fe and 3.69 ppm Mn was found in LB (Luria–Bertani) bacterial medium. The generation of
reactive oxygen species (ROS) was monitored in distilled water and bacterial medium and showed that
FeMnO3 particles do not generate O2c
  ions with or without UV irradiation, but synthesize H2O2 and
show an antioxidative effect. Besides the higher stability of FeMnO3 particles in aqueous solution they
showed an inhibitory effect on Bacillus subtilis growth in LB medium even at low concentrations
(0.01 mg ml 1), but not in BHI medium even at 1 mg ml 1. This study points out that the mechanism of
antibacterial action of engineered metal oxides needs continued investigation and specific experimental
controls
