By using newly developed layer-by-layer self-assembly of Fe3O4 nanocrystals on substrates with synthesis of binder molecules between nanocrystals creating new adsorption sites on the nanocrystals in monolayer, nanocrystalline monolayer was fabricated on the nanocrsytalline monolayer. This result indicates that essensially, the number of layers of nanocrystalline films that are uniformly fabricated on the substrates is able to be controlled by doing the steps sequentially.
