Research interests include optical sensors for biomedical applications, metal nanoparticles, plasmonics, chemical and bio-sensing, fiber optic sensors. Current research mainly focuses on Localized Surface Plasmon Resonance properties of gold microcrystals and the development of LSPR and SERS based fiber optic sensor for bio-applications.

 

Fabrication of large area flexible transparent conducting electrodes (TCE) which find numerous opto-electronic applications using various industrially scalable low process cost methods such as rod coating, screen printing, roll to roll coating etc., which is crucial in the advances in opto-electronics. Emphasis will be on the scaling up as well as extension of crack lithography for the roll to roll large area TCEs as it offers possibilities of cost reduction without compromising the performance in direct industrial applications.
