Targeted drug delivery is a hot topic of research. Scientists around the world are working on different ways to get drugs into specific cells without negatively impacting the rest of the body. Now researchers in England and Germany have created gold-studded polymer microcapsules that release compounds into cells by rupturing when exposed to ultraviolet light. The capsules could be useful for researchers studying the effects of drugs on cells, and eventually they could perhaps serve as a tool. (source: technologyreview.com)
