Method Separates Hybrid Nanoparticles
A magnet-assisted chromatographic method may make it easier to purify certain complex nanoparticles, according to work presented on Aug. 31 at the American Chemical Society national meeting in Denver.
Such nanostructures—in which tiny magnetic particles are stuck to other particles to form complexes that resemble dumbbells or flowers, for example—are under investigation for medical, catalytic, and diagnostic uses. But many of the reactions researchers rely on to make the multipart particles are complex and can . . .
