Study on Electrochemical Glucose Sensing Based on MWCNTs/GOx/LIG Electrodes
Diabetes mellitus is a major challenge in the global public health field,and its early diagnosis and dynamic monitoring are of great significance for disease management. In this paper,a glucose sensor based on laser-induced graphene(LIG) electrode modified by carbon nanotube-enzyme complex was constructed. A 3D patterned graphene three-electrode system was prepared by laser direct writing technology. The aminated multi-walled carbon nanotubes(N-MWCNTs) and glucose oxidase(GOx) were covalently bound and modified to the surface of the working area of the LIG electrode by glutaraldehyde. The current response of glucose on the composite electrode was determined by chronoamperometry. The results showed that the cross-linking of N-MWCNTs could effectively improve the sensitivity of glucose sensors. The prepared composite electrode had a good current response to glucose solution in the range of 0.5×10
-6
-5×10
-3
mol/L concentration,and the detection limit was 0.5×10
-7
mol/L. The sensor exhibits high sensitivity,good precision,repeatability,selectivity,stability and flexibility,and can be used for glucose detection in biological samples such as serum,sweat,urine,etc. The preparation of the LIG immobilized enzyme electrode is simple,green and low-cost,and shows broad application prospects in portable blood glucose detection.
