Non-enzymatic Glucose Sensor Based on CuO Nanoplates

Authors: Chu Thị Xuan*


We have successfully fabricated electrochemical sensor for non-enzymatic glucose measurement based on CuO nanoplates. CuO nanoplates were synthesize by a facile hydrothermal method at 180oC for 23h without using any surfactant. Filed-emission scanning electron microcopy (FE-SEM) and X-ray diffraction (XRD) were used to characterize the morphologies and crystal structures of the synthesized materials. The mixture of CuO nanoplates and polytetrafluoroethylene with mass ratio 0.15:1 was compressed at 100 kg/cm2 to form a disk used as working electrode materials for glucose measurement. Pressed disk electrode fabricated with Pt/CuO nanoplates was evaluated as cyclic voltammetry non-enzymatic glucose sensor in 0.1M NaOH solution. The sensor was able to detect glucose with the concentration as low as 0.1 mM. This result show that the CuO nanoplates are promising candidate for non-enzymatic glucose detection.
