Water-powered, electronics-free dressings that electrically stimulate wounds for rapid wound closure.

Chronic wounds affect ~2% of the U.S. population and increase risks of amputation and mortality.

Adhesive anti-fibrotic interfaces on diverse organs.

Implanted biomaterials and devices face compromised functionality and efficacy in the long term owing to foreign body reactions and subsequent formation of fibrous capsules at the implant-tissue interfaces. Here we demonstrate that an adhesive implant-tissue interface can mitigate fibrous capsule formation in diverse animal models, including rats, mice, humanized mice and pigs, by reducing the level of infiltration of inflammatory cells into the adhesive implant-tissue interface compared to the non-adhesive implant-tissue interface. Histological analysis shows that the adhesive implant-tissue interface does not form observable fibrous capsules on diverse organs, including the abdominal wall, colon, stomach, lung and heart, over 12 weeks in vivo.

Use of Therapeutic RNAs to Accelerate Wound Healing in Diabetic Rabbit Wounds.

Diabetes mellitus (DM) affects over 422 million people globally. Patients with DM are subject to a myriad of complications, of which diabetic foot ulcers (DFUs) are the most common with ∼25% chance of developing these wounds throughout their lifetime. Currently there are no therapeutic RNAs approved for use in DFUs.
