Laser Transmission Spectroscopy for Nanoparticle Characterization

Our biophysics work involves the characterization of nanoparticles in the 1 to 3000 nanometer size range in aqueous suspension using Laser Transmission Spectroscopy and related techniques. There are a number of biological applications to this work including the detection of species-specific DNA in the environment, the characterization of the size of liposomes, the characterization of nanoparticles in cells, the analysis of virus-like proteins, the analysis of sub-cellular nanostructures, and a host of related systems. The analysis of the geometry of mitochondria is currently being considered for the detection of cancer cells.
