US scientists have drawn on the benefits of freeze-dried blood platelets to heal wounds. Freeze-drying blood platelets were made to release human growth factors, which are tiny blood cells that can spur the development of a new layer of skin as a method to heal wounds.
Lead researcher Fern Tablin says that her technique involves removing plasma from blood, and washing away all other blood cells to leave only the platelets.
AdvertisementAccording to her, the platelets are added to polymers and a sugar before being freeze-dried.
She says that the powder would then be feasible to be applied to wounds directly or impregnated into bandages.
The researcher says that such a dressing may help stimulate healing when applied to a wound, reports New Scientist magazine.
