IIT Guwahati researchers
have developed a low-cost, biodegradable, composite, transparent wound-dressing
film that would enable the body to heal on its own through the endogenous
enzymes, according to recent research.
The laboratory-scale development was found to be at least 50%
economical in comparison with similar commercial materials. The research to
address these issues was carried by out a team at the Department of Chemical
Engineering, IIT Guwahati.
Several
promising features and advantages exist for the polymer-based hydrogel films as
novel wound dressing materials. In addition to their bio-degradability that
counters environmental hazards, the mentioned films are easy for people to
afford them. They prevent any kind of toxicity that counters and hampers the
growth of cells, tissues and natural healing processes. Even if the dressing
material loses its occlusivity to bacteria after being swollen under huge flow
of exudates, the material would leach few of its components that facilitate
localized antibacterial effect in a hydrolytic environment.
IIT Guwahati has created the knowledge
framework and associated protocols for successful identification and
optimization of polymer hydrogel films for the probable wound dressing
applications.
Such
customized and effectively designed novel materials provide the necessary hope
to address effectively issues such as biodegradability of synthetic
polymer-based materials among others. All these are expected to further enrich
the on-field applications of polymers in real-world applications.
Compared
to the CA-based PVA-St composite hydrogel film, the recently invented MA-based
similar film has been about 4.56 percent inexpensive.
