Nanoparticle Assembly: Expanding the Realm of the Possible

Nanoparticle Assembly: Expanding the Realm of the Possible

emerging technologies, Materials Science
JACS Spotlights Feb. 22, 2022 Nanoparticles assemble themselves into a multitude of compositions and structures, and the range of possible applications appears almost limitless. Robert Macfarlane and co-workers give an overview of the history and current state of nanoparticle assembly research, focusing on assembly approaches and emergent properties of the resulting materials and summarizing future directions and challenges (DOI: 10.1021/jacs.1c12335). The simplest assembly process, uncontrolled aggregation of nanoparticles into disordered clusters or films, is used on an industrial scale to produce coatings. Supramolecular assembly techniques (in various stages of development) direct nanoparticles to form ordered patterns, self-healing nanocomposites, vesicles, micelles, or thin films. Light, magnetic fields, or biomolecular templates can direct nanoparticles to produce even more complex structures. The resulting materials interact with light, electrons, and magnetic fields in ways…
