Profile

Our lab focuses on developing fluorescence and Raman spectroscopy-based diagnostics. We employ techniques including fluorescence cross-correlation spectroscopy (FCCS), fluorescence resonance energy transfer (FRET), Surface Enhanced Raman Spectroscopy (SERS), etc. for probing.
We also have expertise in designing surface-functionalized gold nanoparticles for therapeutic and diagnostic applications. We are currently studying the efficiencies of such nanoconstructs by confocal imaging, by in-situ probing of single nanoparticle dynamics in live cells and by measuring cytotoxicity at the cellular level prior to testing their efficiencies in vivo.
The major Research Areas of our lab:

1. Designing of metal nanoparticles for drug delivery, receptor targeting, and bioimaging applications.
2. The development of surface enhanced Raman spectroscopy (SERS)-based platforms for disease-diagnosis and for probing the presence of trace amounts of pesticides, carcinogens, pathogens, etc. in samples.
3. Detection of disease-related exosomes (as biomarkers) by FCCS.
