Patchy particles show promise for drug delivery
U. PENN (US)—A team of physicists, chemists, and engineers has demonstrated a novel method for the controlled formation of patchy particles, using charged, self-assembling molecules. The particles may one day serve as drug-delivery vehicles and perhaps be used in small batteries that store and release charge. (more…)
