A NiFe alloy nanoparticle/graphene oxide hybrid (NiFe/GO) was prepared for electrochemical glucose sensing. The as-prepared NiFe/GO hybrid was characterized by transmission electron microscopy (TEM) and X-ray diffraction (XRD). The results indicated that NiFe alloy nanoparticles can be successfully deposited on GO. The electrochemical glucose sensing performance of the as-prepared NiFe/GO hybrid was studied by cyclic voltammetry and amperometric measurement. Results showed that the NiFe/GO-modified glassy carbon electrode had sensitivity of 173 μA mM cm for glucose sensing with a linear range up to 5 mM, which is superior to that of commonly used Ni nanoparticles. Furthermore, high selectivity for glucose detection could be achieved by the NiFe/GO hybrid. All the results demonstrated that the NiFe/GO hybrid has promise for application in electrochemical glucose sensing.

The accurate quantification of glycemic index (GI) remains crucial for diabetes management, yet current methodologies are constrained by resource intensiveness and methodological limitations. digestion models face challenges in replicating the dynamic conditions of the human gastrointestinal tract, such as enzyme variability and multi-time point analysis, leading to suboptimal predictive accuracy. This review proposes an integrated technological framework combining non-enzymatic electrochemical sensing with artificial intelligence to revolutionize GI assessment.

Chemical polymerization/oligomerization opens numerous opportunities, from fundamental materials research to practical applications in catalysis, energy, sensing, and medicine. The electrochemical detection of vitamins B (folic acid) and C (ascorbic acid) requires new approaches because of low selectivity, electrode fouling, and interference from other chemicals. As an excellent material for long-term vitamin detection, oligo 3,5-diamino-1,2,4-triazole (oligo DAT) enhances the sensitivity, selectivity, and stability of sensors by creating a stable, conductive layer that facilitates electron transfer and reduces interference from common substances like glucose or uric acid.

Phthalate esters, particularly di(2-ethylhexyl) phthalate (DEHP), are widely used plasticizers found in various consumer products, posing significant environmental and health risks due to their endocrine-disrupting effects. In this study, a novel enzyme-free intra-capacitive biofuel cell self-powered sensor (ICBFC-SPS) was developed. The ICBFC-SPS integrated a ternary heterostructure-based capacitive anode and a cathode with a sensing interface into a single-chamber electrolytic cell.

The non-enzymatic electrochemical detection of glucose by direct oxidation using electrodes modified with suitable electrocatalysts is now well-established. However, it most often requires highly alkaline media, limiting dramatically the use of such electrodes at neutral pH. This is notably the case of Ni-based electrodes.
