Research Highlights

Research in our nano-chemistry lab is focused on synthesis and biomedical applications of photoactive nanomaterials. These are materials which get activated by light. Principally, we are working on two types of photoactive materials: 1. Luminescent and 2. Plasmonic nanomaterials. The two types of luminescent nanomaterials that have caught our imagination are: a. Semiconductor nanocrystals or quantum dots (QDs) and b. Lanthanide based upconversion nanocrystals (UCNs). We are developing soft chemical routes to obtain water soluble, biocompatible, highly luminescent and stable nanocrystals with narrow size distribution. Amongst Plasmonic nanomaterials, we have developeanisotropic and hollow silver nanocrystals with versatile plasmon tunability from visible to the near-IR spectral region. Such nanocrystals are then utilized for developing new non-invasive biomedical techniques for cancer diagnosis and treatment based on synergistic imaging and therapy of deep-seated tumours. Plasmonic photocatalysis using hollow silver nanocrystals is another area which looks quite promising.
