基于层状二硫化钼-石墨烯构建新型17β-雌二醇电化学生物传感器
A Novel Electrochemical Bioensor for 17β-estradiol Based on MoS2-Graphene Nanocomposite
摘要
Abstract
MoS2‐graphene nanocomposite was prepared .A novel electrochemical biosensor was constructed by immobilizing of aptamer on the electrode that was modified with Au nanoparticles and MoS2‐graphene .The electrochemical behavior of the modified electrode was tested by cyclic voltammograms ,differential pulse volta‐mmetric and electrochemical impedance .The reaction time and temperature between 17β‐estradiol and aptamer were optimized .The experimental results showed that the proposed assay exhibited a good linear relationship between the peak current and the concentration of 17β‐estradiol in the range of 1 .0 × 10 - 11 ~ 1 .0 × 10 - 8 mol/L with the detection limit of 5 .0 × 10 - 12 mol/L .The biosensor had good selectivity and stability .关键词
