Laser-Controlled Switch Turns Blood Clotting On, Off

Facebook Twitter LinkedIn Email
CAMBRIDGE, Mass., July 26, 2013 — Laser-controlled gold nanoparticles that release DNA molecules to switch blood clotting on and off could help doctors better control blood clotting in patients undergoing surgery, or promote wound healing. Natural blood clotting is produced by a long cascade of protein interactions, culminating in the formation of fibrin, a fibrous protein that seals wounds. Surgery, wound healing and other conditions require manipulation of this process, typically through the use of anticoagulants such as heparin and warfarin. Administering blood thinners reduces clotting, but reversing their effects...Read full article
