“…Commercial SPEs and a MWCNT‐modified carbon‐ceramic electrode were used for the analysis of food and pharmaceutical samples, respectively. B 6 was also determined in several samples (multivitamin tablets, corn flakes, energy drinks, cerebrospinal fluid and blood) using a pencil electrode modified with a molecular imprinted polymer using bimetallic magnetic nanoparticle as platform . Finally, as already mentioned, simultaneous determination of B 6 and B 2 was proposed.…”

Vitamins are a chemically heterogeneous group of compounds known as essential for the normal functioning of the organic metabolism. Their decrease in humans can lead to several diseases and not being produced by the body, they need to be obtained from dietary sources or supplements. For these reasons, their determination in food, pharmaceutical and clinical samples is crucial. This article reviews key advances in electrochemical measurements of vitamins over the past decade. Particular attention is given to papers proving applicability to real samples analysis. The technical features of the proposed sensors are presented and discussed along with their analytical performances. Future trends and challenges are also addressed.

Herein we report the detection of an anti‐HIV drug Nevirapine (NVP) through a sensitive electrochemical method using efficient electro‐active 2D materials; Palladium nanoparticles supported reduced graphene oxide (rGO), i.e., Pd@rGO, MoS2 quantum dots (QDs) and Pd@rGO decorated with MoS2 QDs modified electrodes. We have shown an interaction between Pd@rGO and MoS2 QDs in the composite based on FT‐IR and UV‐Vis. absorption studies. The interaction between Pd@rGO and MoS2 QDs in designed material leads to highly efficient electro‐activity that is actually responsible for the broad spectrum quantification of frequently used anti‐HIV drug Nevirapine. The electrochemical oxidation behaviour of NVP is studied using cyclic voltammetry (CV) over bare glassy carbon electrode and modified electrodes with alone Pd@rGO and MoS2 QDs and finally over designed material Pd@rGO/ MoS2 QDs. The excellent catalytic effect is observed over designed material as evident from oxidation at relatively lower potential of 0.65 V vs. Ag/AgCl and large peak current in comparison with others. Pd@rGO/ MoS2 QDs modified electrode exhibits a linear increase in oxidation peak current with an increase in NVP concentration in the range of 0.1 – 80 μM with limit of detection (LOD) of 50 nM at signal‐to‐noise ratio (S/N): 3. The developed sensing platform shows excellent stability and sensitivity to make it suitable for the determination of NVP in the complex system.

“…Molecule such as pyridoxine (PN) with three terminal hydroxyl groups can be used as an efficacious solution to receive star‐like polymers . Pyridoxine (next to pyridoxal, pyridoxal 5‐phosphate, and pyridoxamine) belongs to the hydrosoluble B 6 vitamin group and is responsible mainly for the transference of amino acid groups, acting as a coenzyme .…”

The vitamin B 6 -based macroinitiator was prepared for the first time by the transesterification reaction of pyridoxine with 2-bromoisobutyryl bromide. A pyridoxine-based star-shaped block copolymer with a hydrophilic pyridoxine core and a dual hydrophilic poly(2-(dimethylamino)ethyl methacrylate)-block-poly(N-isopropylacrylamide) arms was synthesized for the first time via a simplified electrochemically mediated atom transfer radical polymerization, utilizing only 20 ppm of catalyst complex. The rate of the polymerizations was controlled by applying appropriate potential/current values during electrolysis to prevent the possibility of intermolecular coupling of the polymer stars. The asymmetric star polymers showed narrow molecular weight distribution (Đ = 1.09-1.13).1 H NMR spectral results confirm the formation of star-like block (co)polymers. These new vitamin B 6 -based eagle-shaped star (co)polymers may find biomedical and biosensor applications as pH-sensitive and thermo-sensitive drug delivery systems.
