Summary: In this study, a novel coumarin derivative-modified cellulose acetate (DCB-CA) was synthesized as a fluorescent probe for the highly selective and sensitive determination of CN- in food samples. Different characterization methods were used to analyze the DCB-CA, and it showed a significant fluorescence response to CN- with a distinct color change. The detection limit of CN- using DCB-CA was much lower than the recommended threshold limit by the World Health Organization. The favorable solubility and processability of CA allowed for the easy fabrication of different fluorescent materials, including films and coatings, for CN- detection.

Summary: This study presents a label-free electrochemical sensing method for D-Mannitol in biological samples using a MAO-modified GCE sensor, demonstrating a wide linear detection range, low detection limit, excellent selectivity, reproducibility, and stability. The sensor's enhanced performance is attributed to the electrocatalytic property of MAO and the presence of oxy functional groups, making it a promising platform for developing low-cost, high-performance bioanalytical sensing systems.

Summary: In this study, localized and electrochemically assisted nylon-6,6 deposition was achieved at a three-phase junction by increasing the pH using electrochemical water reduction. The polycondensation reaction between 1,6-hexanediamine and adipoyl chloride occurred spontaneously at the liquid-liquid interface. This system design allows for very localized polyamide deposition.

Summary: Two benzodiazepine type drugs, nitrazepam and 7-aminonitrazepam, were studied at the electrified liquid-liquid interface (eLLI). The structure of these illicit sedative drugs allows for molecular charging, enabling them to cross the eLLI interface. The drugs were investigated using both macroscopic and microscopic eLLI, with detection limits and voltammetric detection sensitivity derived from experimental data. The developed methodology successfully detected the drugs in pharmaceutical formulations and spiked biological fluids.

Summary: Due to the negative charge of rose bengal (RB) molecule, its entry into cells is hindered. This study investigates the involvement of organic anion transporting polypeptides (OATPs) in cellular uptake of RB. Experimental analysis and simulations indicate that RB only interacts with the surface of cellular membranes and requires OATPs for intracellular transport. The differences in uptake of RB in liver and intestinal cell lines suggest the importance of OATPs in cellular uptake.

Summary: In this work, the possibility to electrochemically assist and study the interfacial polycondensation is presented. Polyamides are synthesized at the liquid-liquid interfaces as a consequence of the transfer of partly protonated diamines from the aqueous to the organic phase. The interfacial formation of polyamides was tested using macroscopic and microscopic systems, and the modified interfaces were assessed using various analytical techniques.
