Self-Assembly of Lithographically Patterned Nanoparticles

Year: 2009

Type: article

Abstract: The construction of three-dimensional (3D) objects, with any desired surface patterns, is both critical to and easily achieved in macroscale science and engineering. However, on the nanoscale, 3D fabrication is limited to particles with only very limited surface patterning. Here, we demonstrate a self-assembly strategy that harnesses the strengths of well-established 2D nanoscale patterning techniques and additionally enables the construction of stable 3D polyhedral nanoparticles. As a proof of the concept, we self-assembled cubic particles with sizes as small as 100 nm and with specific and lithographically defined surface patterns.
