IIT-G invents biodegradable lowcost composite wound dressing film

A team of researchers at the Indian Institute of Technology, Guwahati (IIT-G) has invented a biodegradable low-cost composite transparent wound dressing film. The material, based on the integration of a synthetic polymer, is nontoxic and will create a moist environment that would enable the body to heal on its own through the endogenous enzymes, according to recent research. IIT-G has created the knowledge framework and associated protocols for successful identification and optimisation of polymer hydrogel films for the probable wound dressing applications. Such customised and effectively designed novel materials provide the necessary hope to address issues such as biodegradability of synthetic polymer-based materials, cost of raw materials and processes, utilisation of expensive natural polymers to achieve functional materials, and biocompatibility of developed products, among others. The laboratory scale-based retail cost of the optimised composite hydrogel film has been about Rs 0.188/sq cm, which is about 66 per cent inexpensive in comparison with similar commercial materials that costs Rs 0.565 /sq cm.
