New Adhesive Bandage Based on Fetal Skin’s Healing Abilities

Scientists from Harvard and McGill University in Canada have developed a new form of active adhesive dressing their research suggests will have a positive effect on the speed and efficacy of wound treatment and healing. It will do so by recapturing the natural ability of fetal skin to regenerate, close wounds and heal rapidly without leaving a scar.

The research team reported that to replicate the healing functions of prenatal skin, which usually fade with age, the new active adhesive dressings (AAD) include adhesive hydrogels that are tough and stretchable, capable of adhering to tissue, and perform an antimicrobial function that increases the healing capacity of the skin. The hydrogels are thermoresponsive and therefore activated by exposure to body heat.

Tests done so far have indicated that the new dressing is capable of speeding up wound closure and healing time when compared to other bandages, and there were no inflammatory or immune system responses to indicate that using the AAD dressings on living tissue would be unsafe. The dressings have yet to undergo human trials before being released to the market.
