Microparticles offer a promising way to deliver multiple doses of a drug or vaccine at once, because they can be designed to release their payload at specific intervals. However, the particles, which are about the size of ...

Heat and light create new biocompatible microparticles

Biomedical engineers at Duke University have devised a method for making small particles that are safe for living tissues that will allow them to create new shapes attractive for drug delivery, diagnostics and tissue engineering.
