    摘要: In a method of generating a nanocrystal with a core-frame structure, a seed crystal, including a first substance, is exposed to a capping agent. The seed nanocrystal has a plurality of first portions that each has a first characteristic and a plurality of second portions that each has a second characteristic, different from the first characteristic. The capping agent has a tendency to adsorb to portions having the first characteristic and has a tendency not to adsorb to portions having the second characteristic. As a result, a selectively capped seed nanocrystal is generated. The selectively capped seed nanocrystal is exposed to a second substance that has a tendency to nucleate on the plurality of second portions and that does not have a tendency to nucleate on portions that have adsorbed the capping agent, thereby generating a frame structure from the plurality of second portions of the seed nanocrystal.

    摘要: Methods for forming nanostructures of various shapes are disclosed. Nanocubes, nanowires, nanopyramids and multiply twinned particles of silver may by formed by combining a solution of silver nitrate in ethylene glycol with a solution of poly(vinyl pyrrolidone) in ethylene glycol. Hollow nanostructures may be formed by reacting a solution of solid nanostructures comprising one of a first metal and a first metal alloy with a metal salt that can be reduced by the first metal or first metal alloy. Nanostructures comprising a core with at least one nanoshell may be formed by plating a nanostructure and reacting the plating with a metal salt.
