摘要：

What a clean-up! A scalable method for the purification of nanoparticles in nonaqueous media has been developed that is based on reversible electrophoretic deposition (see picture). In this electropurification process, nanoparticles of varying size, shape, composition, and ligand environment can be electrodeposited onto an electrode surface, washed, and subsequently redispersed in as little as two minutes.
