Application of graphene/graphene oxide in biomedicine and biotechnology

Abstract

Graphene, a truly two-dimensional (2D) and fully π-conjugated honeycomb network, exhibits many unique physical and chemical properties that are interesting in a wide range of areas. Since its discovery in 2004, graphene has been extensively studied in many different fields including nano-electronics, composite materials, energy research, catalysis and so on. Based on the fascinating action of members in the carbon family, notably zero dimensional (0D) fullerenes and one dimensional (1D) carbon nanotubes (CNTs) in biomedical areas, increasing number of reports have explored the potential of graphene for different biomedical and biotechnical applications since 2008. This manuscript aims to provide a summary of current research progress of graphene-based carbon materials in biosensing, drug (gene) delivery and tissue engineering, and discusses the opportunities and challenges in this rapidly growing field.
