ABSTRACT
This work demonstrates the formation of highly stable electrochemically reduced graphene oxide (ERGO) thin films on indium tin oxide (ITO) substrates through electrochemical reduction of colloidal suspension containing graphene oxide in deionized water. The structural details, and bio-compatible interactions of the resulting uniformly distributed ERGO/ITO surfaces are studied using various microscopic and spectroscopic characterization tools. Lipase enzyme is immobilized onto the ERGO surface for detection of triglyceride in tributyrine solution. The currently developed ERGO with enhanced electronic properties demonstrates compatibility for establishing specific interaction with various functional groups and could be used as a suitable surface for pursuing experiments in selective detection of bio-entities.
