Carbon Nanotubes Ferry Proteins into Cells

Abstract:
Reporting their work in the Journal of the American Chemical Society, Hongjie Dai, Ph.D., and graduate student Nadine Wong Shi Kam, have shown that acid-oxidized single-walled carbon nanotubes will bind proteins and transport them through the cell membrane. Acid-treated carbon nanotubes are stable in water and do not aggregate, as do untreated carbon nanotubes. The nanotubes cross the cell membrane via endocytosis, a process that cells use to transport a variety of molecules into the cell.
