Nanoparticle Arrays: Selective Assembly of Sub-Micrometer Polymer Particles (Adv. Mater. 25/2010)
A directed self-assembly approach to fabricate multiple-particle arrays on template surfaces is presented. The colored SEM image shows deposited 200, 350, and 500 nm polystyrene particles, which are sequentially assembled from aqueous suspensions at size-selective assembly sites in work reported by Heiko Wolf and co-workers on p. 2804. Particle size dependent capillary and confinement forces that act at the menisci of the suspensions were harnessed to afford selectivity. Once selectively assembled, the particles were transferred in a one-step printing process.
