Nanocrystals By The Kilogram
Kilogram-scale batches of uniform-sized nanocrystals can be prepared via a simple synthesis procedure, according to researchers in South Korea. The availability of a low-cost method for making bulk quantities of monodisperse (single-sized) nanocrystals may speed up development of nanotechnology applications. Several methods for preparing monodisperse nanocrystals have already been reported, but typically those methods yield gram quantities of product and require size-sorting steps.
