▎ 摘　　要

Graphene oxide, a century old material has attracted the interest of researchers owing to its specific 2D structure and unique electronic, optical, thermal, mechanical and electrochemical properties. The recent advancements in the field of biotechnology and biomedical engineering are targeted at exploring the biosensing applications of graphene oxide due to its biocompatibility. It is considered to be one of the most versatile materials, with wide range of applications which can be tailored by functionalization of the different oxygen containing groups present in the structure. In this review the focus is on the biosensing applications of graphene oxide, detection of analytes with high sensitivity and selectivity. This would give insight into the designing of feasible protocols for the analysis of therapeutic diseases and environmental safety, thereby improving the quality of human life. (C) 2015 The Authors.
