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). According to a recent article published in the *Journal of Nanomedicine*, the team has developed a novel, biodegradable fluid capable of stopping bleeding within seconds. This innovation could revolutionize emergency medicine and surgical procedures.
The material is primarily composed of a protein fragment known as a polypeptide. When applied to an open wound, the polypeptide 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 not only effective but also highly biocompatible and non-toxic.
In laboratory trials involving various types of tissue—such as the brain, liver, skin, spine, and small intestine—the peptide-based fluid demonstrated remarkable efficacy in halting bleeding almost immediately. The researchers suggest that this material could be particularly useful in high-stress environments like battlefield surgeries or emergency trauma care. It also performs well in moist conditions, which is a significant advantage over many existing hemostatic agents.
Importantly, the material does not trigger an immune response in animals, indicating its potential for widespread use. However, the exact mechanism by which the polypeptide achieves such rapid hemostasis remains unclear. Further research is needed to fully understand how the gel forms and functions at the cellular level.
This development marks a major step forward in medical science, offering a promising solution for controlling severe bleeding in both clinical and real-world settings. As the research progresses, it may soon become a standard tool in emergency medicine and surgery. Information sourced from Shanghai Medical Devices.
