Research synopsis

My current research focus is the development of materials for biomedical applications. We recently developed a method for preparing polysaccharide-polyamine crosslinked hydrogels. We are currently exploring their application as anti-microbial and wound healing materials. We are also working on the development of curcumin based biomaterials as antibacterial agents and cancer therapeutics.
