South Korean Researchers Develop Rapid-Healing Wound Powder

South Korean researchers have developed a wound-healing powder that rapidly forms a protective, scab-like layer upon application to an injury [1, 2].

This innovation addresses the limitations of conventional medical patches, which often have fixed shapes that do not fit irregular or deep wounds. By providing a flexible, antimicrobial, and anti-inflammatory dressing, the powder allows for better coverage and protection of complex injury sites [1, 2].

The research team includes Prof. Jang Woo-young of the Korea University Anam Hospital Orthopedic Department and senior researcher Ryu Jin from the Korea Institute of Science and Technology (KIST) [1, 2]. The powder is composed of chitosan and polyacrylic acid, two materials that work in tandem to accelerate the healing process.

"Chitosan plays an anti-inflammatory and antimicrobial role, while polyacrylic acid helps with wound healing," Jang said ^[1].

The powder's effectiveness relies on a chemical reaction between the material and the skin. Ryu Jin said the powder binds well to the wound area due to the chemical bonding between the functional groups on the skin and those in the powder hydrogel ^[1].

In blood clotting experiments, the material demonstrated a rapid response, forming a protective barrier in approximately two minutes ^[1]. This speed is critical for stabilizing wounds and preventing further contamination or blood loss in emergency or surgical settings.

The development marks a shift toward more adaptable wound-care solutions. Unlike adhesive bandages, the powder conforms to the exact geometry of the wound, ensuring that no gaps are left exposed to the environment [1, 2].
