Self-assembly and self-organization are of great interest for the creation of micro- and nanostructured patterned surfaces by bottom-up approaches. By transferring mixed Langmuir monolayers of a phospholipid (DPPC) with small ad-mixings of other components onto solid substrates large area chemical patterns structured in the meso- up to the nanoscale can be created. These patterns can provide the basis for further chemical modification to form topographical or more complex chemical structures. We present the transfer of DPPC mixed with different dyes yielding luminescent stripe patterns as a proof of concept. Furthermore, transferred patterns composed of DPPC and alkoxyamines followed by polymerization of the pattern yield structured polymer brushes. The concept should be expandable to various other substances opening a wide field of possible applications in biological science and surface modification.
