Insulin helps to speed the recovery of "severe burns and other kinds of serious wounds such as traumatic bone fractures."
One of the challenges in biomedicine however is the delivery of a localized release of therapeutic medicine. Now "researchers at Northwestern University have demonstrated an innovative method for delivering and releasing the curative hormone at a specific location over a period of time. The nanodiamond-insulin cluster holds promise for wound-healing applications and could be integrated into gels, ointments, bandages or suture materials."
Substantial amount of insulin can be loaded onto the nanodiamonds, which have a high surface area. The nanodiamond-insulin clusters, by releasing insulin in alkaline wound areas, could accelerate the healing process and decrease the incidence of bacterial infection.
