1. A method comprising: disposing an ink mixture comprising a first patterning compound and a second patterning compound on a nanoscopic tip, wherein the first patterning compound and the second patterning compound are adapted to phase separate from each other on a surface, contacting the nanoscopic tip with the surface, wherein transport of the first and second patterning compounds occurs together from the nanoscopic tip to the surface to produce on the surface a phase separated structure comprising the first and second patterning compounds.
