At P-NAS lab we focus on novel ideas pertaining to the synthesis and use of various nanoparticles in healthcare. We believe in the ideology of multidisciplinary collaborations which enables us to integrate newer approaches. Nanotechnology has shown immense potential in tackling problems of modern medicine in recent times, but yet there remains many unanswered questions .........
