In general, several aspects on the above-mentioned problems are monitored with steady state and time resolved fluorescence spectroscopy. Ultrafast photo-processes and solvent response towards the formation of the transient species are probed with transient absorption and fluorescence up-conversion techniques in collaboration with several research groups in India & abroad. The experimental results are often supported with ab-initio/DFT calculations, molecular docking and molecular dynamics (MD) simulation. Recently, we are interested in the development of non-covalently functionalized nanoconjugate system and assess their potentiality as drug delivery and drug repurposing agent in multiple disease domains, including neurodegenerative disorders.
