Artificial platelet mimics developed by a research team from Case Western Reserve University and University of California, Santa Barbara, are able to halt bleeding in mouse models 65 percent faster than nature can on its own.
By mimicking the shape, size, flexibility and surface chemistry of real platelets, artificial platelets are pushed out of the main blood flow to vessel walls. There, the surface chemistry enables them to anchor on damaged cells and induce faster clotting at the site.
