Russian scientists develop advanced collagen sponge to stop bleeding, fight infection

Scientists at Penza State University in Russia have announced the development of an experimental collagen-based sponge aimed at stopping bleeding, stabilizing blood clots, and inhibiting bacterial growth.

The research team explained that the new sponge combines three main functions: assisting in stopping bleeding, preventing premature breakdown of blood clots, and combating bacteria. This could lead to more effective medical tools for bleeding control and reducing infection risks.

How the sponge works and its components

The sponge is built on a three-dimensional porous structure made of collagen, a key protein in the body's connective tissues. This structure helps absorb fluids and activates the body's natural clotting mechanisms to stop bleeding.

Experts noted that the sponge contains aminocaproic acid, which helps stabilize blood clots, as well as vancomycin and ciprofloxacin, two antibiotics used to limit bacterial growth.

Manufacturing process and clinical trials

The manufacturing process involves several stages, starting with preparing the collagen and adding active ingredients, followed by freezing and freeze-drying the material. This technique preserves the sponge's porous structure, allowing for the controlled release of medical components when needed.

Researchers are continuing to improve the sponge's formulation and production techniques, with clinical trials currently underway in preparation for its approval for medical use.
