Using infinitesimal particles of gold, researchers have discovered a way to stop blood from clotting, and then make it clot again. The technique could greatly improve surgical procedures, said Kimberly Hamad-Schifferli, a bioengineer at the M.I.T. Lincoln Laboratory who was involved with the research. She and her colleagues reported their findings in the journal PLoS One.
Today, surgeons rely on blood thinners like heparin to prevent clots from forming during operations. These thinners do a good job with clot prevention, but then take time to wash out of the bloodstream.
