| Popis: | Randomly distributed colloidal magnetic nanoparticles in solution are polarized in the presence of an external magnetic field, and the interparticle dipole–dipole attraction drives their assembly into linear chains. In this Communication, we report using a model A3-coupling reaction, that the field-directed self-assembly of gold-coated magnetite (Fe3O4@Au) nanoparticles can be used to remotely control the rate of reaction by manipulating their colloidal assembly of catalyst in situ. |
