Controlled Gold Nanoparticle Placement into Patterned Polydimethylsiloxane Thin Films via Directed Self-Assembly

Scheme 1

Schematic of directed self-assembly stage setup used for (a) high evaporation and (b) low evaporation experiments. (c) Shows the location on the syringe pump where the cage is attached. (d) Shows an example of a drop of AuNPs pinned by the fixed superstrate at the beginning of a high evaporation self-assembly experiment. (e) Shows the superstrate used for the low evaporation self-assembly experiments.
