Magnetic Nanoparticles Can Stop Internal Bleeding

Internal bleeding should be taken seriously, and not just because it could indicate signs of severe trauma. This form of hemorrhage, which occurs in blood vessels far away from the skin (e.g., between internal organs) can deprive tissues affected of nutrients and oxygen, thus, increasing the risk of adverse events such as ischemia or necrosis.

The novel intervention is believed to incorporate the magnetic properties of custom-made iron nanoparticles. The team helped deliver a dose of pro-clotting molecules to an experimental analog of an internal hemorrhage.

The scientists involved in this study argued that this kind of work could increase the efficacy and efficiency with which internal bleeding is stopped. This could also help bring down the mortality rates associated with such events.

The materials were a type of iron oxide (magnetized Fe3O4, which the researchers termed 'Ferria') combined with the enzyme, thrombin. This treatment was also packaged in a hydrosol-gel for delivery into the body. The Ferria compound could also be magnetized for controlled delivery to the desired location once in the body.

Also, this procedure has not yet been tested in humans. It may be some time before we find out if this interesting response to the problems posed by internal bleeding is safe and acceptable for use in human patients.
