Cover Feature: The Role of Surface Chemistry in Impedimetric Aptasensing (ChemElectroChem 23/2018)

Abstract

The Cover Feature shows how the surface chemistry can influence the electroanalytical performance of graphene oxide nanocolloids used as a platform for the impedimetric detection of Ochratoxin A. By electrochemically tuning the amount of oxygen functionalities on the material surface, a better sensitivity is achieved when using a more reduced platform.
