A novel amperometric biosensor based on ZnO nanoparticles-modified carbon paste electrode for determination of glucose in human serum.
本研究开发了一种基于氧化锌纳米粒子(ZnONPs)修饰碳糊酶电极(ZnONPsMCPE)的安培型葡萄糖生物传感器。葡萄糖氧化酶(GOx)被固定于ZnONPs/石墨/石蜡油碳糊中,ZnONPs为GOx提供生物相容微环境,并促进GOx与电极之间的电子转移。检测时,GOx催化葡萄糖氧化生成过氧化氢(H2O2),在+0.4 V(vs. Ag...
