摘要

In this study, the electric double layer (EDL) modulated FET biosensor is demonstrated with impedance analysis. The unique sensor design allow protein to be detectable in high ionic strength solution. The enhanced EDL created by applying higher gate voltage is the key role to modulate the FET, causing the high sensitivity. AC impedance analysis is introduced to demonstrate the capacitance nature in our sensor system. The transduction signal of C-reactive protein (CRP) detection is dominated by imaginary part of impedance. With enhanced EDL and high transconductance of FET, this novel technology allow protein to be detectable in physiological sample without any sample pretreatment.
