Controlled Crystalline Assembly of Nanocubes

The bottom-up approach of self-assembling nanoparticles is a promising strategy for fabricating desired nanostructures. However, current methods that utilize ligands and physical/chemical stimuli to control the forces between particles have certain limitations, such as limited material selection or the use of a fluidic template. Thus, novel approaches in nanoparticle assembly are necessary for future applications.<br/> In this study, we explore the synthesis and assembly of gold nanocubes with a focus on achieving controlled morphology and crystalline structure. Representative cases of assembled structures are presented using gold nanocubes. These advancements could open new ways for further expansion, including optics, sensing, imaging, and catalysis.
