- Abstract
In this work, Ni@Pt core-shell nanoparticles with diameter of 3-4 nm and thin Pt shell was synthesized by a successive reduction approach using carbon as support to develop high-performance non-enzymatic glucose sensor. The resulting electrochemical sensor displayed good catalytic activity toward glucose oxidation, presenting a high current density of 66.9 µA mM−1 cm−2 at an applied potential of −0.1 V. It showed a wide linear range of 0.1-30.1 mM and the limit of detection was down to 30 µM ( S/ N=3). Notably, it was found that the proposed sensor exhibited good selectivity to avoid the interference from ascorbic acid, uric acid, fructose and acetamidophenol. Furthermore, the feasibility of the as-prepared non-enzymatic glucose sensor in the determination of glucose in serum samples was successfully implemented.
