Dr. Sai Sathish Ramamurthy, Asst. Professor, STAR Lab, Dept. of Chemistry, SSSIHL in collaboration with Dr. Shivakiran Bhaktha B N, Photonics Lab, IIT Kharagpur and alumnus SSSIHL, have been working on amalgamation of plasmonic and photonic crystal-based sensing technologies.
The novelty of this work is the creation of a highly precise platform for the detection (1 femtomolar) of environmentally hazardous aluminium ions in drinking water. In common parlance, it is not just the equivalent of finding a needle in a haystack, but even the eye of the needle. This is done using nanocavities; ‘hot-spots’ as they are called.
