This entry summarizes several approaches to the large-scale synthesis of metal nanostructures with various well-defined shapes by controlling the chemistry in solutions. The strategies include preferential adsorption of capping reagents on different crystallographic planes, use of self-assembled surfactant molecules as templates, control over the plasmonic excitation, and template-engaged replacement reaction. The as-synthesized nanostructures have well-controlled shapes and exhibit unique properties compared to their bulk material. They are promising candidates for applications in a range of fields that include optoelectronics, photonics, sensing, clinical diagnostics, catalysis, and energy storage/conversion.
