Researchers from Penza State University in Russia have developed an experimental sponge made of collagen, aimed at helping to stop bleeding and enhance the stability of blood clots, while also reducing bacterial growth, a step that may contribute to developing new means of controlling bleeding and reducing infection risks.
The Russian website Gazeta.ru reported, citing the Russian Ministry of Education and Science, in a report published yesterday Tuesday, that the sponge combines three functions: helping to stop bleeding, reducing early breakdown of blood clots, and combating bacteria, noting that researchers continue to work on improving its composition and manufacturing methods in the laboratory.
The sponge relies on a three-dimensional porous structure of collagen, a fundamental protein that enters into the formation of connective tissues in the body and helps support their structure. The pores help absorb fluids, while collagen helps activate natural clotting mechanisms that assist in stopping bleeding.
According to the report, the sponge contains aminocaproic acid, which reduces clot breakdown and helps stabilize them, in addition to two substances, vancomycin and ciprofloxacin, which are antibiotics used to combat certain types of bacteria.
The manufacturing of the sponge goes through several stages, including preparing the collagen and adding active ingredients, then freezing the material and freeze-drying it. This technique helps preserve its porous structure, allowing for the release of active ingredients.
The project is still in the laboratory development stage, as researchers work on improving the sponge's composition and production technology. Clinical trials are currently being completed to approve it for medical use.
