Ultrasound and magnetism let drug-delivery nanobeads travel upstream

Although various groups are already working on nanoparticles that could be used for directed drug delivery via the bloodstream, most of those particles are designed to "go with the flow." Now, however, Swiss researchers have created ones that can actually travel upstream.Continue ReadingCategory: ScienceTags: ETH Zurich, Nanoparticles, Drug delivery, Magnetism, Ultrasound
