Popis: Micropatterning typically involves a multistep lithographic process. Despite its high throughput and versatility, lithography involves multiple steps and hazardous etching chemicals. Moreover, lithographic techniques fall short in creating nonidentical, noncrystalline microarrays on solid surfaces. In this work, we demonstrated a bottom-up patterning of microlens arrays using dropwise condensation (DWC) of functional monomers. Inspired by the DWC of water on surfaces such as leaves, substrates were exposed to vapor of the desired composition at certain conditions. Droplets comprising silane monomers were produced with moderate temperature (
