Lavik and co workers made platelets from polymers already used in treatments approved by FDA. They also built the parts of the synthetic platelets that bind to natural platelets from relatively short pieces of proteins (asthey're more stable than longer pieces and cheaper). To avoid formation of an artificial clot, each synthetic platelet is built with a surrounding water shield. Fluorescing compounds showed the synthetic platelets not bound in clots were flushed from the rat model's system in a day. No ill effects were seen in the following week......
