Selective assembly of sub-micrometer polymer particles

Abstract

(Figure Presented) A directed self-assembly approach is presented to fabricate multiple-particle arrays on templates with a dedicated design. The SEM image shows deposited 200-nm, 350-nm, and 500-nm polystyrene particles, which are sequentially assembled from aqueous suspensions at designated assembly sites in a sizeselective manner.
