Researchers of IIT Guwahati prepared a special bandage to recover from injury

Researchers from the Indian Institute of Technology (IIT) Guwahati have got a major breakthrough in the direction of recovery from injury. In fact, researchers have invented such a transparent film (bandage) that is biodegradable as well as economical.

According to the team that invented it, its material based on the integration of synthetic polymers is not harmful to nature. Also, this material creates a moist environment, which is able to heal the injury on its own through the enzymes of the body. The cost of preparing it at the laboratory level is 50 percent less than the present bandages. Findings related to this invention have been published in the International Journal of Biological Macromolecules.

According to Aritra Das, PhD Scholar at IIT Guwahati, cotton wool, lint and gauze (mesh bandage) are commonly used in wound healing materials. They are used to stop wound leakage and speed up the healing process. However, a major disadvantage of such materials is that they can also damage the right tissue(s). Because of this, the researchers worked towards finding a better alternative.

Prepared in this way: According to Das, this invention has the potential to make a big impact in this field. We focused on the integration of a synthetic polymer, namely polyvinyl alcohol (PVA) with the natural polymer starch (ST), to prepare it, to form an economical, biodegradable, non-toxic and transparent composite hydrogel. According to the researchers, this product has the ability to inhibit the growth of bacteria in the injury even after it has become inflamed under a hydrolytic environment.

Develops healthy cells and tissues: According to Professor Chandan Das, Department of Chemical Engineering, IIT, Guwahati, this new material helps in the growth of healthy cells and tissues, apart from providing them with a suitable environment for repair of injured cells. Is. Researchers said that it has been prepared in the laboratory. Its initial results have been good. However, more work is still needed on this.

This film will prove beneficial in many ways

According to the researchers, this film prepared in the lab can prove to be beneficial in many ways. Firstly, it has been prepared using malic acid, not citric acid. Due to this the wounds will be cured sooner as well as the cost of preparing it will also be reduced.
