Bolaamphiphile nanotubes : from gene delivery to nano-electronics

Keywords

Raman effect, Self assembly (Chemistry)

Abstract

We report a new bolaamphiphile nanotube assembly and its interesting pH dependent structural transformation between tubule and helical structure. The transformation mechanism was probed by Raman microscopy, X-ray crystallography and molecular modeling. The tubule to helix structural transformation was examined for DNA release application in gene therapy. These self-assembled bolaamphiphile nanotubes are also used as templates for metal deposition to fabricate metallic nanowires. Raman microscopy analysis proved that non-hydrogen bonded amide groups, which are part of the bolaamphiphile nanotubes, can capture metal ions and form stable metalamide complexes. These complexes seem to become efficient nucleation sites and produce uniform metallic coatings around the bolaamphiphile nanotubes. The metallic nanowires can be applied to the construction .of nano-electrical circuits, since the nanowires can be attached. on Au electrodes via self-assembled carboxylic acid thiol monolayers.
