Synthetic red blood cells mimic natural ones, and have new abilities

Scientists have tried to develop synthetic red blood cells that mimic the favorable properties of natural ones, such as flexibility, oxygen transport and long circulation times. But so far, most artificial red blood cells have had one or a few, but not all, key features of the natural versions. Now, researchers have made synthetic red blood cells that have all of the cells' natural abilities, plus a few new ones.
