Advances toward bioapplications of carbon nanotubes

Bioapplications of carbon nanotubes have been predicted and explored ever since the discovery of these one-dimensional carbon allotropes. Indeed, carbon nanotubes have many interesting and unique properties potentially useful in a variety of biological and biomedical systems and devices. Significant progress has been made in the effort to overcome some of the fundamental and technical barriers toward bioapplications, especially on issues concerning the aqueous solubility and biocompatibility of carbon nanotubes and on the design and fabrication of prototype biosensors. In this article we take a comprehensive look at the advances in this fast-moving and exciting research field. We review the current status of…
