Abstract
A method and a sensor for detecting L-cysteine based on a 3,3'-dithiobis (1-propanesulfonate)-mercury composite membrane are provided. The method includes: implanting a p-well and an N-type substrate on field effect transistor substrate, constructing a source electrode and a drain electrode at the p-well, constructing a silicon dioxide layer on the substrate, plating an aluminum-copper alloy layer, a chromium-palladium alloy layer, and a gold film layer on a polysilicon gate substrate, constructing a silicon nitride layer on the substrate and the silicon dioxide layer; extending a gate part; preparing an ethanol solution of disodium 3,3′-dithiobis (1-propanesulfonate), cleaning and soaking gate gold electrode in the solution, followed by soaking in an ethanol solution of mercuric nitrate, and then washing the gate gold electrode; connecting electrode interfaces, inserting the electrode into PBS, and connecting power interfaces to a stabilized voltage supply, connecting a signal output interface to a multimeter.
