A portable micro glucose sensor based on copper-based nanocomposite structure

摘要: Precisely detecting the concentration of glucose in human body is an attractive way to prevent or treat diabetes. Portable sensors with non-enzymatic catalytic materials have received great attention recent years. Herein, a facile strategy for fabricating high-performance electrochemical sensor proposed. A three-electrode integrated device based on CuO nano-coral arrays/nanoporous Cu (NCA/NPC) designed and fabricated. The portable NCA/NPC exhibits high activity glucose. performance derives from excellent conductivity NPC substrate electrocatalytic arrays. This sensitivity 1621 μA mM−1 cm−2 linear range 0.0005–5.0 mM, low detection limit 200 nM (S/N = 3), fast response time 3 s, good anti-interference performance, repeatability considerable stability detection. work will certainly provide efficient structure proper material choices future sensors.
