A label-free electrochemical immunosensor for beta-amyloid detection

Abstract

A label-free detection of beta-amyloid (βA) proteins using an electrochemical immunosensor fabricated <italic>via</italic> immobilizing specific anti-beta-amyloid antibodies (An-βA-Abs) onto an interdigitated electrode of gold (IDE-Au) modified using a self-assembled monolayer (SAM) of dithiobis(succinimidyl propionate) [DTSP] is presented here.
