Nanosphere Lithography: A Powerful Method for the Controlled Manufacturing of Nanomaterials

Figure 14

SEM micrographs of some typical examples of polygonal aggregates that were formed by templating PS beads against 2D arrays of cylindrical holes. The cylindrical holes used in all experiments are ≅2 μm. (a) Dimers with 1.0 μm PS beads; (b) trimers with 0.9 μm PS beads; (c) square tetramers with 0.8 μm PS beads, and (d) pentagons with 0.7 μm PS beads. “Reprinted with permission from [116].
