New rapid hemostatic material successfully developed
Release date: 2006-11-03
A groundbreaking advancement in hemostatic technology has been made by a team of 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*, they have developed a novel biodegradable fluid capable of stopping bleeding almost instantly. This innovation could revolutionize emergency care, especially in high-risk environments like battlefield surgery.
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 fully healed, the gel naturally degrades into amino acids, which are then absorbed by the body for tissue repair. This makes it a completely safe and eco-friendly solution with no toxic byproducts.
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. The results were impressive—bleeding was stopped within seconds across all tested tissues. The researchers believe this material could be particularly useful in surgical settings where quick and effective hemostasis is critical, such as in trauma or battlefield medicine.
Another key advantage of the new material is its ability to function effectively in humid conditions, which is crucial for real-world applications. Additionally, it did not trigger any immune response in the animals tested, suggesting it may be well-tolerated in humans as well.
Despite these promising findings, the exact mechanism by which the fluid achieves rapid hemostasis remains unclear. Further research is needed to fully understand how the polypeptide interacts with different tissues and how its properties can be optimized for broader medical use. Nevertheless, this discovery marks a significant step forward in the development of advanced, biocompatible hemostatic agents. (Shanghai Medical Devices)
