“We're very enthusiastic about this work as a result of, for the primary time, we are able to create a library of tiny, encased vaccine particles, every programmed to launch at a exact, predictable time,” says professor Robert Langer. Credit score: Courtesy of the Langer lab MIT engineers have invented a brand new Three-D fabrication technique that may generate a novel kind of drug-carrying particle that might permit a number of doses of a drug or vaccine to be delivered over an prolonged time interval with only one injection. The brand new microparticles resemble tiny espresso cups that may be stuffed with a drug or vaccine after which sealed with a lid. The particles are manufactured from a biocompatible, FDA-approved polymer that may be designed to degrade at particular instances, spilling out the contents of the "cup." "We're very enthusiastic about this work as a result of, for the primary time, we are able to...
