基于功能化边缘改性石墨烯表面修饰的葡萄糖电化学生物传感器的构筑
Construction of an Electrochemical Biosensor for Glucose Based on Functionalized Edge-modified Graphene Surface Modification
摘要
Abstract
To achieve rapid and highly sensitive detection of glucose,two-dimensional carbon-based nanomaterials functionalized edge-modified graphene(FG)were used as a conductive carrier and glucose oxidase(GOx)as a biorecognition molecule to construct a high-performance electrochemical biosensor for glucose detection(GCE/FG/GOx/CS).The electrochemical sensing performance of GCE/FG/GOx/CS electrodes was investigated using cyclic voltammetry and time-current methods.The sensing electrodes showed good electrosensing performance,high sensitivity(46.85 μA·mmol·L-1cm-2),and a wide linear detection range(0.05～1.60 mmol·L-1)for glucose,with a detection limit as low as 2.37 μmol·L-1.In addition,the electrode showed good selectivity,reproducibility(n=7,relative standard deviation RSD=2.05％),cycling stability,and storage stability(97.09％retention of response current after one week).The recoveries were 98.5％～104.4％for glucose determination in actual beverage samples.The method is simple,highly selective,and sensitive,providing a theoretical basis for the rapid detection of glucose content in food.关键词
