New 'self-exploding' microcapsules could take sting out of drug delivery
Belgian chemists have developed "self-exploding" microcapsules that could one day precisely release drugs and vaccines inside the human body weeks or even months after injection. The study, by researchers at Ghent University and the Universit? Catholique de Louvain, ...K-State's Culbertson receives $530,000 National Science Foundation award
