▎ 摘　　要

Graphene's unique properties have made it a popular candidate for nanomaterial based biosensors. Its remarkable characteristics have led to its rapid development in the electrochemical biosensing, field effect transistors, and optical biosensing as well as the creation graphene-metal nanoparticle hybrids for improved performance. This article comprehensively reviews the most recent trends in graphene-based biosensors and attempts to identify the future directions in which the field is likely to thrive. (C) 2011 Elsevier B.V.
