Nanomaterials: One layer at a time
The properties of a material depend on its architecture — this is perhaps best exemplified by the dramatically different behaviours of graphite, graphene and carbon nanotubes. With the advent of nanotechnology, arranging materials into specific, organized structures at the nanoscale has become increasingly important. This issue is discussed here by Katsuhiko Ariga and co-workers, who emphasize the versatility of the layer-by-layer technique. Sheets are first separated from the bulk and assembled differently, sometimes with other components. They can be layered on substrates through electrostatic interactions but also covalent, coordination or hydrogen bonds, and the layer-by-layer procedure can also be carried out in different ways, such as dipping, spin coating or spraying. All of this enables the formation of structures with a wide variety of morphologies, properties and applications, including in the biomedical field.
