Smarter Anti-Clotting Tools

Description

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 findingsin the journal PLoS One.
