Interfacing Carbon Nanotubes with Biological Systems: From Biosensors to Cellular Transporters

This talk will discuss two relatively new topics in carbon nanotube research. The first is nanotubes for chemical and biological sensors, an exploration motivated by the ultra high surface area of single walled carbon nanotubes and the need for label free electronic detectors for a wide range of molecules in gas and liquid environments. I will discuss the fabrication of nanosensor devices, chemical functionalization schemes for imparting selectivity and the physical mechanisms involved in the detections. The second topic is about interfacing carbon nanotubes with living systems. I will show our recent observation of carbon nanotube internalization into living cells, and nanotubes as carriers for transporting proteins inside cells. The implications of these results will be discussed.
