• polydimethylsiloxane (PDMS) (Sylgard 184, Dow Corning) was used to transfer OTS to the substrate through a physical mask of latex spheres. A drop (10–12 µL) of an OTS solution in bicyclohexyl was deposited onto a clean, dry block of PDMS (2 × 2 cm2). A 30 µL volume of a 40% v/v solution of OTS in bicyclohexyl was
