A groundbreaking advancement in hemostatic technology has been made by researchers from the Massachusetts Institute of Technology (MIT) and the University of Hong Kong (HKU), as reported in the *Journal of Nanomedicine*. The team has developed a novel, biodegradable fluid capable of stopping bleeding within seconds, offering a promising solution for emergency and surgical settings.
The material is primarily composed of a protein fragment known as a polypeptide. When applied to an open wound, it rapidly self-polymerizes into a protective gel that seals the injury and promotes healing. Once the wound has healed, the gel safely degrades into amino acids, which are naturally absorbed by the body and used for tissue repair. This makes the substance both effective and environmentally friendly.
In a series of experiments on rodents, the peptide-based fluid was tested on various types of wounds, including those on the brain, liver, skin, spine, and small intestine. In nearly all cases, the treatment successfully stopped bleeding almost immediately. Researchers suggest that this could be especially valuable in high-stress environments such as battlefield surgeries or emergency medical situations where quick intervention is crucial.
Another key advantage of the material is its ability to function effectively in moist conditions without triggering an immune response in the test animals. This suggests potential for broad application in human medicine with minimal side effects.
Despite these promising results, the exact mechanism by which the polypeptide achieves rapid hemostasis remains unclear. Further research is needed to fully understand how the gel forms and interacts with different tissues. However, the discovery marks a significant step forward in the development of advanced wound care solutions.
