Facile Non-Enzymatic Electrochemical Sensing for Glucose Based on CuO-BSA Nanoparticles Modified GCE.

Transition-metal nanomaterials are very important to non-enzymatic glucose sensing because of their excellent electrocatalytic ability, good selectivity, the fact that they are not easily interfered with by chloride ion (Cl), and low cost. However, the linear detection range needs to be expanded. In this paper, CuO-bovine serum albumin (BSA) core-shell nanoparticles (NPs) were synthesized for the first time in air at room temperature by a facile and green route.
