Reversible Biogel with Inverse Temperature Response for Nano- and Bio-encapsulation

The unique properties of carbon nanotubes (CNT), more specifically, single walled carbone nanotubes (SWNT), have made them excellent candidates for applications in bio-sensing, fuel cells, and nanofabrication. Considerable research effort has been devoted to development of methods to achieve stable suspensions of highly dispersed CNTs. However, progress has been impeded by two major hurdles. FIrst, their poor solubility in both aqueous and organic solvents makes them difficult to manipulate and functionalize.
