Herein, an electrochemical assay developed by differential pulse voltammetry (DPV) in combination with the disposable pencil graphite electrode (PGE) was progressed for sensitive and selective detection of gluten. Under the optimum experimental conditions, a linear concentration range of gluten was obtained from 20 to 100 μg/mL and consequently the detection limit was found to be 7.11 μg/mL. In addition, this electrochemical assay was successfully employed for the detection of gluten in different flour samples. Applicability of our method was also tested in the commercial samples of vinegar and baker's yeast.

Herein, first, MIL-125 samples were synthesized via a hydrothermal method. Then, Ag species were doping on the surface of MIL-125 samples via the photolysis of silver nitrate. Finally, the Z-scheme MIL-125/Ag/BiOBr composite was synthesized via a directed liquid assembly method.

Point of Care (POC) diagnosis provides an effective approach for controlling and managing Neglected Tropical Diseases (NTDs). Electrochemical biosensors are well-suited for molecular diagnostics due to their high sensitivity, cost-effectiveness, and ease of integration into POC devices. Schistosomiasis is a prominent NTD highly prevalent in Africa, Asia, and Latin America, with significant socioeconomic implications such as discrimination, reduced work capacity, or mortality, perpetuating the cycle of poverty in affected regions worldwide.

The preparation and modification of porous electrodes are an important component of the new generation electrochemical oxidation technology. Rapid preparation of porous electrodes can be easily achieved by synchronous oxygen bubble electrodeposition. However, according to the reaction mechanism of lead dioxide anodic electrodeposition, there is bound to be a competitive reaction of adsorbed hydroxyl radicals in the oxygen bubble template method, which means that synchronous OER impacts both the surface morphology and potentially the crystalline structure of the metal oxides.

Automated, rapid electrocatalyst discovery techniques that comprehensively address the exploration of chemical spaces, characterization of catalyst robustness, reproducibility, and translation of results to (flow) electrolysis operation are needed. Responding to the growing interest in biomass valorization, we studied the glycerol electro-oxidation reaction (GEOR) on gold in alkaline media as a model reaction to demonstrate the efficacy of such methodology introduced here. Our platform combines individually addressable electrode arrays with HardPotato, a Python application programming interface for potentiostat control, to automate electrochemical experiments and data analysis operations.

Poor wear- and corrosion-resistance of 316L SS implants are critical problems in orthopedic implants. This study aims to improve the wear- and corrosion-resistance of 316L SS through surface coating. In this study, a bilayer composite coating consisting of polyether ether ketone (PEEK) as the first layer, and titania (TiO)- and Cu-doped mesoporous bioactive glass nanoparticles (Cu-MBGNs) were deposited as the second layer on a 316L SS electrophoretic deposition (EPD).
