铜纳米颗粒修饰柔性石墨构建无酶葡萄糖传感器
Preparation and performance of electrochemical glucose sensors based on copper nanoparticles loaded on flexible graphite sheet
摘要
Abstract
A flexible graphite sheet can be used as a self-supported substrate material for sensors owing to its excellent conductivi-ty and flexibility. Copper nanoparticle/flexible graphite sheet self-supporting enzyme-free glucose sensors were prepared by a hydro-thermal method using copper sulfate as the elemental copper source and ascorbic acid as the reducing agent. Results indicate that both the molar ratio of copper sulfate to ascorbic acid and the hydrothermal temperature affect the microstructure and sensor perform-ance. The optimal sensor obtained with a ratio of 1:0. 5 at 150 ℃ has a low detection limit of 1. 05 μmol/L, and high sensitivities of7254.1 μA·mM-1·cm-2(R2= 0.9961)from0.1to3.4 μmol/Land3804.5 μA·mM-1·cm-2(R2= 0.9995)from3.4to 5. 6 μmol/L. The sensor possesses excellent anti-interference properties against sodium chloride, acetaminophenol, ascorbic acid, dopamine, and uric acid, and has good reproducibility.关键词
