Achilles heel: Popular drug-carrying nanoparticles get trapped in bloodstream
Date:2/5/2013

nospheres to the vessel wall, releasing them upon attachment. But the simpler approach may be nanoparticles of different shapes, which might escape the red blood cells on their own.

Eniola-Adefeso and her team are experimenting with rod-shaped nanoparticles.

"A sphere has no drift," she said, so nanospheres won't naturally move sideways out of the red cell flow. "When a rod is flowing, it drifts, and that drift moves it closer to the vessel wall."
