(Scientific American is part of Nature Publishing Group.) [...]

Mimicking red blood cells to improve drug delivery

synthetic red blood cells

Biomedical breakthroughs rarely outdo nature itself—despite our ever-increasing knowledge of new materials and processes. So that’s why one group working on drug dispersal is looking, not to novel delivery systems, but rather to replicate the natural dynamics of blood cells. By devising a flexible, biodegradable microparticle that looks and acts like a red blood cell, [...]
