RNA-coated bandages speed chronic-wound healing

05/29/2013 | GMA News (Philippines)

Bandages coated with short interfering RNA were found to speed healing of chronic wounds, such as those associated with diabetes and cancer, according to MIT researchers. The scientists found an effective way to deliver the siRNAs directly to the wound by alternately dipping standard bandages into solutions of protamine sulphate and calcium phosphate nanoparticles bound to the siRNAs. When activated on the wound by the body's humidity, the siRNAs stopped production of a protein that destroys collagen, which is needed for healing.
