Abstract
The present technology provides an illustrative method for preparing shaped nanoparticles. The method includes passing a metal vapor to a shaping apparatus and condensing the metal vapor within the shaping apparatus to form selectively-shaped metal nanoparticles. The method may also include forming the metal vapor by heating a bulk metal. In an embodiment, the shaping apparatus comprises a mesh separator that include a plurality of nano-sized, square-shaped pores or a plurality of shaping cups that includes a plurality of recesses.
