Figure 1:

(A,B) Schematic of gold nanoparticle (AuNP) self-assembly at the liquid-liquid interface (A), and the chemical lift-off lithography (CLL) process on the assembled AuNP monolayer (B). (C) Schematic of the interactions that occur during CLL. (D-I) Optical images (D, E, F), and scanning electron microscopy (G, H, I) of a polydimethylsiloxane (PDMS) patterned stamp after lift-off (left) and the corresponding complementary negative image imprinted in the AuNP monolayer donor substrate (right). Additional images can be found in Figure S4.
