Abstract:Surface engineering of human hair was successfully used as a self-supported electrochemical sensor to detect glucose in human serum. Polydopamine (PDA) was firstly grafted on hair by oxidative self-polymerization of dopamine and then the copper nanoparticles (CuNPs) were electrolessly deposited to achieve surface metallization of hair (hair@CuNPs). The hair@CuNPs composites with uniformly dispersed conductive layer in 8 µm thickness exhibited outstanding electrocatalytic activity towards glucose oxidation. Und… Show more
