Researchers at the National University of Quilmes (UNQ) in Argentina have engineered a 'smart' bandage designed to accelerate wound healing, offering a proactive approach compared to conventional dressings. This research has been published in *Pharmaceutics*.
According to Ayelén Sosa, a fellow at Conicet (National Scientific and Technical Research Council), the bandage is composed of a natural biopolymer, gelatin, and incorporates an emulsion with antimicrobial and healing medications. It not only absorbs fluids and allows the wound to breathe but also actively prevents infections and promotes cell regeneration.
The transparent film adheres easily to the skin and can absorb up to four times its weight in liquids. The emulsions contain nanoparticles and silver sulfadiazine to inhibit bacterial growth, vitamins A and E to promote healing, and lidocaine for anesthetic effects. Preclinical studies on mammalian models are planned to evaluate the bandage's healing effects before potential clinical trials.
