Non-enzymatic sensing of glucose with high specificity and sensitivity based on high surface area mesoporous BiZnSbV-G-SiO2

Abstract

It is profoundly appealing to build a common enzyme-free sensor for detection of glucose. We effectively synthesized a uniform and mesoporous BiZnSbV-G-SiO2 (BZSVGS) quaternary nanocomposite by electrodeposition on a Ni foam substrate. This BiZnSbV-G-SiO2@NF composite terminal has been used as an electrocatalyst for coordinated oxidation of glucose, in this manner acting as a high-performance non-enzymatic glucose sensor. Coordinated electrochemical estimation with the as-arranged anodes in PBS and urea showed that the BiZnSbV-G-SiO2 nanocomposite has a great electrocatalytic movement toward glucose oxidation in a neutral medium and a wide straight reaction from 0.06 to 0.1 μmol/L, a low detection constraint of 0.06 μmol/L (S/N = 3) at a low connected potential of + 0.20 V vs Ag/AgCl. This ponder moreover highlights the effect of diminishing anion electronegativity on upgrading the electrocatalytic proficiency by bringing down the potential required for glucose oxidation and long-term steadiness together with a brief reaction time of roughly 4 s highlights the promising execution of the BiZnSbV-G-SiO2@NF anode for non-enzymatic glucose detection with high accuracy and unwavering quality. Besides, it can be used for glucose location in human blood serum, promising its application toward assurance of glucose in genuine tests.
