Optical Spectroscopy and Dynamics of Nanostructures

Optical microscopy incorporated with spectroscopy is a very powerful approach to study nanostructures. In this talk, I will present a few examples of our recent work in this direction. One is optical characterization of single rare-earth ion doped nanoparticles, which show strong near-infared to visible upconverted photoluminescence. The unique characteristics of these nanoparticles suggest that they could serve as ideal single-molecule probes for bio-imaging. Another is on graphene, a two-dimensional (2D) carbon material and the mother of 1D carbon nanotubes.

Functional Dendritic Architectures

Polymeric nanostructures have gained broad interest for the targeted delivery of drugs.[1] Dendritic polymers are especially attractive candidates for encapsulating or conjugating diagnostic and therapeutic agents, particularly dendritic polyglycerol because of its low toxicity and high biocompatibility.[2] Furthermore, polyglycerols have also been evaluated for their extremely protein resistant properties on surfaces.[3] For in vivo applications, the selected dendritic nanotransporters will have to be water-soluble and non-toxic.
