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 University Catholique de Louvain, is scheduled to appear in the Jan. 9, 2006, print issue of the American Chemical Society's journal Biomacromolecules.
