DNA电化学传感器中电极修饰条件的探讨
Modified conditions of DNA electrochemical sensor
摘要
Abstract
Objective To investigate the best preparation condition of ssDNA single-layer film. Methods A DNA modified gold electrode was obtained with the technology of self-assembled monolayer( SAM). The concentration of DNA and the time of modification were studied by cyclic voltammetric technique. Results The results showed that a SAM was formed on the surface of gold electrode. The best SAM could be obtained in 80 μmol/L capture fixed for 12 h. Conclusions The generation of sulfur gold key could form a stabilized SAM in gold electrodes.关键词
