Magic bullets: A drug-loaded structure comprising a PEGylated (PEG=polyethylene glycol) gold nanoshell on silica nanorattle spheres (GSNs; see picture) combines remote-controlled photothermal therapy with chemotherapy. Tumor cells are killed with higher efficacy and less toxicity than the free drug.
