Biosensing on a graphene oxide surface

Abstract

This article describes our recent research on a selective protein detection system built on a graphene oxide (GO) surface. Our original idea is to fix pieces of GO on a solid support. This enables direct observation of chemical reactions occurring on the GO surface and on-chip device fabrication. The basic principle can be applied to other proteins as well as other biological molecules simply by changing the molecules to be modified, which makes GO a versatile platform for integrated biosensing devices.
