Researchers at the Centre for Incubation, Innovation, Research and Consultancy (CIIRC) at Jyothi Institute of Technology in south Bengaluru have come up with a product that can stop bleeding in 90 seconds. They have even applied for a patent for this new product.
M S Santosh, along with Divakara M Bhas has developed this product which is a carboxyl-linked graphene sponge (DAPGS). Earlier, Axiostat, a sponge patented by city-based Leo Sebastian Mavely of Axiom was being supplied to the Indian Army and a few other armed forces. Axiostat could stop bleeding in 3-4 minutes.
While Axiostat uses chitosan, a naturally occurring polymer (found in shellfish) which stops profuse bleeding in a few minutes, the graphene sponge uses medicinal amino acid and a biocompatible protein that has been extracted from a tree. Santosh said that the protein derived from the bongamia tree which is used in the graphene sponge also helps to prevent infection.
According to Santosh, the unique feature of the DAPGS is that it not only that it inherits the remarkable liquid absorbability from the cross-linked graphene sponge, but also enhances the interfacial stimulating ability to blood cells, thus promoting blood coagulation.
The product is commercially viable as it uses low cost material like graphene and amino acid which are easy to synthesise.
