Nanowerk  February 28, 2018 Researchers in Russia used magnet-driven nanoparticles consisting of two key components – thrombin, an enzyme responsible for blood clotting and magnetite. Thrombin interacts with the protein called fibrinogen and triggers clot formation to block the damaged vessel. The thrombin is wrapped into a special porous matrix made of magnetite that allows for precise control of the movement of particles inside the body using an external magnetic field. A drug based on these nanoparticles is nontoxic and can be injected intravenously and delivered straight to the site of a vascular injury. It can accelerate local clot formation […]
