EMSL Project ID

Abstract
One focal point in advanced materials research has been the use of integrated molecular systems to accomplish specific tasks. The unique mechanical, optical, and electronic characteristics of nanomaterials have stimulated enormous interest as bio- and chemical sensors, elements of molecular electronics, and in drug delivery. Many of these applications require the construction of functionalized carbon nanotubes and an understanding of the mechanisms of intermolecular interaction in these structures. In this proposal, we study several new chemical and optical sensors based on single wall carbon nanotubes (SWNT) functionalized with specific recognition elements. Our goals include:
- study of ion and molecular recognition structures based on surface modified carbon nanotubes with covalently attached crown ethers,
- study of light control of the conductivity of single wall carbon nanotube films.
The proposed research is based upon our expertise in studies of carbon nanotubes and mechanisms of light induced redox reactions in nanosystems including semiconductor nanoparticles and bilayer vesicular systems.
