Electrochemical characteristics of aptasensor based on MEMS thin-film gold electrode

摘要：

　　A new fabrication methods of thin-film gold electrode is reported.Electrochemical characteristics of self-assembly aptasensor based on MEMS thin-film gold electrode has been studied by lots of experiments,characteristics include immobilizing time,AC impedance,CV curves.Experiments indicate immobilizing time of DNA-SH on gold electrode is more than 15 hours.CV curves and AC impedance of MEMS thin-film gold electrode show the same conclusion that 20μm/L DNA is optimum concentration when DNA is immobilized on gold electrode.Those results present a potential universal method for other aptasensors.
