Photos of PULSED platform and McHugh lab (IMAGE) Rice University Caption An array of hollow microparticles (left) developed in the laboratory (top right) of Rice University bioengineer Kevin McHugh for timed-release drug delivery. The particles, which are shown loaded with colored dye, are small enough to fit through a standard hypodermic needle (bottom right) and designed to biodegrade over time, releasing their drug payload at a later target date.
