Using Carbon Nanotubes For Molecular Transport

Molecular transport across cellular membranes is essential to many of life's processes, for example electrical signaling in nerves, muscles and synapses. In biological systems, the membranes often contain a slippery inner surface with selective filter regions made up of specialized protein channels of sub-nanometer size. These pores regulate cellular traffic, allowing some of the smallest molecules in the world to traverse the membrane extremely quickly, while at the same time rejecting other small molecules and ions.
