With the rise in public health awareness, research on point-of-care testing (POCT) has significantly advanced. Electrochemical biosensors (ECBs) are one of the most promising candidates for the future of POCT due to their quick and accurate response, ease of operation, and cost effectiveness. This review focuses on the use of metal nanoparticles (MNPs) for fabricating ECBs that has a potential to be used for POCT. The field has expanded remarkably from its initial enzymatic and immunosensor-based setups. This review provides a concise categorization of the ECBs to allow for a better understanding of the development process. The influence of structural aspects of MNPs in biocompatibility and effective sensor design has been explored. The advances in MNP-based ECBs for the detection of some of the most prominent cancer biomarkers (carcinoembryonic antigen (CEA), cancer antigen 125 (CA125), Herceptin-2 (HER2), etc.) and small biomolecules (glucose, dopamine, hydrogen peroxide, etc.) have been discussed in detail. Additionally, the novel coronavirus (2019-nCoV) ECBs have been briefly discussed. Beyond that, the limitations and challenges that ECBs face in clinical applications are examined and possible pathways for overcoming these limitations are discussed.

A new nanocomposite containing Ni(II) ions, electrochemically reduced graphene oxide (ERGO) and poly (p‐aminobenzenesulfonic acid) (Pp‐ABSA) on pencil graphite electrode (PGE) was prepared using electrochemical deposition coupled with self‐assembly accumulation method and characterized with different techniques. The electrochemical behavior and electrocatalytic activity of modified PGEs were investigated. The Ni/Pp‐ABSA/ERGO/PGE showed a unique electrocatalytic oxidation through an Electrochemical‐Chemical (EC’) pathway for methanol in alkaline media (Jpf=7.04 mA cm−2 and Eonest=0.38 V) compared to Ni/PGE, Ni/Pp‐ABSA/PGE and Ni/ERGO/PGE. The obtained results showed that the self‐assembled incorporation of Ni(II) ions in Pp‐ABSA/ERGO film prepared on PGE surface produced a stable modifier with high electrocatalytic activity towards methanol oxidation. In conclusion, the introduced method for the preparation of Pp‐ABSA/ERGO‐based nanocomposites can open a new, cheap and simple way to design a high‐performance electrocatalyst for direct methanol fuel cell systems.

Here, we report the fabrication of Heterometallo‐supramolecular polymer (H‐SMP) for the selective oxidation of nitrite with the investigation of some kinetic parameters by the complex formation of Co(II) and Fe(II) salts with the symmetrical ligand which is composed of terpyridine moieties specially referred to as [4′,4′′′′‐(1,4‐Phenylene)bis(2,2′:6′,2′′‐terpyridine)] to form polyCoFe. The characterization of polyCoFe was carried out using UV‐Vis titration, FT‐IR and SEM. The viscosity measurement of H‐SMP was utilized to calculate its molecular weight using Mark‐Houwink‐Sakurada equation. The electrochemical performance of polyCoFe_GCE was evaluated using the CV and EIS techniques. The kinetics of the irreversible electro‐oxidation mechanism were investigated by introducing variations in scan‐rate and pH. The concurrence observed between the experimental and simulated CV results provided additional evidence supporting the accuracy and reliability of the determined kinetic parameters. We investigated the efficiency of polyCoFe_GCE for nitrite detection at various concentrations using CV as well as amperometry methods. The amperometric technique showed a wide linear range of 0.66 to 194.15 μM and a low detection limit of 0.11 μM. In addition, modified electrode underwent interference, stability, and reproducibility tests. Real samples were analyzed using both CV and amperometry methods, and the obtained results were compared with those obtained from standard solutions.
