摘要：

Copper nanoparticles (CuNPs) encapsulated by polymeric stabilizer of polyvinylpyrrolidone (PVP) (noted as PVPCuNPs) were simply prepared and used to construct an enzymeless glucose sensor on a solid substrate. Sensing and assay performance of the CuNPs-based sensor to glucose were evaluated in detail. Cyclic voltammetry (CV), chronoamperometry (I-t) and flow injection amperometry (FIA) revealed a high sensitivity, excellent stability, and good reproducibility in the glucose determination at +0.45 V, which was 200 mV more negative than those in former reports. A detection limit as low as 1.0 x 10(-8) M (signal-to-noise =3) and a linear range of 1.0 x 10(-1) M to 5.0 x 10(-3) M were obtained in this study.
