Alex Star’s research interests are in areas of molecular recognition and nanotechnology enabled chemical and biological sensing. For single-walled carbon nanotubes, every atom is on the surface and exposed to the environment; even small changes in the charge-environment can cause drastic changes to their electrical/optical properties. Unique properties of carbon nanotubes such as high electrical conductivity, intrinsic fluorescence, remarkable strength, and anisotropic shape make them a powerful platform for chemical and biological sensing. This research will yield a prospect of building novel detection methods for widest possible range of chemical and biological analytes.
