IASST re­searchers de­velop heal­ing ban­dage

BioSpectrum (India) - - SCIENCE NEWS -

Re­searchers at the In­sti­tute of Ad­vanced Study in Sci­ence and Tech­nol­ogy (IASST), Guwa­hati, have fab­ri­cated a smart ban­dage ma­te­rial that can heal wounds bet­ter and faster and has an­timi­cro­bial prop­er­ties. The ban­dage is made of cot­ton patch coated with chi­tosan­based hy­dro­gel that is loaded with cur­cumin and graphene ox­ide. The re­searchers used cur­cumin as a model drug and the same can be re­placed with other an­timi­cro­bials.

The nano­size of graphene ox­ide al­lows large amount of drug to be loaded on to the patch. Ac­cord­ing to the re­search team, graphene ox­ide also in­creases the strength of the patch es­pe­cially when it gets wet. Cur­rently, there is no con­trol over drug re­lease. The team is try­ing to ad­dress this by us­ing dif­fer­ent nano­ma­te­ri­als. The re­searchers want to make sure that like graphene ox­ide, the cho­sen nano­ma­te­rial is bio­com­pat­i­ble and does not get re­leased into the wound.
