Functionalized carbon nanotubes: Towards the delivery of therapeutic molecules

In the last decade, carbon nanotubes (CNT) have attracted the attention of several scientists, due to their unique and intriguing structure and properties. This is because it is possible to modify them, through several procedures, with a wide variety of molecules. The present report is focused on the potential applications of functionalized CNT (f-CNT) as viable delivery devices. In particular, the recent integration of CNT into biological systems has suggested their potential employment in the delivery of therapeutic molecules, such as drugs, antigens and genes.
