| Abstract: | In this research,we prepared a flexible GOD-PDMS-AuNPs electrode based on good biocompatibility of the PDMS-AuNPs surface.The catalytic performance of glucose in PBS buffer solution was studied with chronoamperometry.The results showed this modified electrode with a significant catalytic ability for glucose and the response current was linear with glucose concentrations in the range of 0.66 mM～100 mM. |
