摘要：Accurate and convenient detection of human glucose level is an effective method for early diagnosis of diabetes and prevention of complications. The flexible electrochemical glucose electrode with low cost, fast responsiveness, good stability, reliability, and high sensitivity has attracted much attention in the monitoring of glucose concentration. The preparation of a conductive layer with catalytic activity on a flexible substrate is the key to make a flexible glucose electrode. Here, we have successfully prepared graphene composite materials sintered with copper nanoparticles on a polyimide film by direct laser writing, and fabricated a flexible non-enzymatic glucose electrode using laser-ablated graphene (LAG) as a conductive electrode. The Cu/LAG electrode exhibits high catalytic activity for glucose. The glucose electrode shows a linear relationship with the sensitivity of 0.708 mA mM-1 cm-2 in 0.05-1.5 mM. In addition, The Cu/LAG electrode also exhibits excellent response time(～2s). The electrode has good application potential and can be used to monitor glucose in human sweat. ? 2022 SPIE.
