Research
The Polymer Nanobiomaterial Research Laboratory focuses on the development of functional polymers for broad range of applications in material science and biomedicine. Specific interest focused in the design and synthesis of bioresponsive polymers, prodrugs, nanogel and hydrogels. Our effort includes the development of novel block copolymers through the modern CLRP techniques and click chemistry strategies, stimuli-responsive hydrogel and nanogels based on natural and biocompatible synthetic polymers for drug delivery, and wound healing applications. We also investigate to develop biocompatible and degradable polymer-based scaffold biomaterials for tissue engineering applications.
