The research work in the Raman Tweezers laboratory involves the application of Raman Spectroscopy combined with Optical Tweezers for recording and studying the Raman signal from trapped micro beads, nano particles and single live cell like RBC, WBC, Stem cell etc. This is the first set up in India which coupled Raman Spectroscopy with Optical Tweezers. The setup has been effectively used to study and characterize the chemically induced oxidative stress in Erythrocytes(RBCs) and nanoparticle induced toxicity in stem cells.
The Raman Tweezers facility was designed and assembled by our researchers through the generous funding from the “Department ofBiotechnology (DBT)” under the project entitled “Biomedical engineering of single cells with a combination of Raman spectroscopy and Optical tweezers”. This is one of the joint research programmes in collaboration with TIFR.
