In the world of drug development, honing an effective molecule is just the first step. As everyone in the drug delivery business knows, issues like solubility, permeability and targeting can be vexing challenges to getting treatment where it needs to go. But what if you could deliver drugs the same way the body dispatches white blood cells to fight infection, or the same way a virus proliferates throughout the body?

That’s what researchers at U.S. universities are working on, aiming to develop synthetic cells that could target ailments and release drugs to treat them. As Popular Mechanics reports, scientists at the University of Pennsylvania are using plastics to build artificial white blood cells called leuko-polymersomes, which would be guided by synthetic molecules designed to mimic the natural receptors white blood cells use to find enflamed tissues and stick to them.
