Nanotube Interactions with Nanoparticles and Peptides
Abstract
Understanding of interactions between single-walled carbon nanotubes and other materials is critical for developing a new technology of self-assembling carbon nanotubes into electronics or drug delivery systems. We demonstrate for the first time the use of nanotube electrodes to manipulate nanoparticles in solution using dielectrophoresis. On the other hand, to understand a non-electrical assisted interaction, we investigate the binding affinity of carbon nanotubes and peptides via combinatorial phage display technique. We find a tryptophan rich binding motif to nanotubes on solid silicon substrates. The motif resembles an alpha helix with tryptophan concentrated along one side that binds non-covalently via interactions to the walls of the nanotube.
