  • This entry describes and reviews the body of work mainly from our group in regard to meso- to nanoscale stripe patterns prepared by Langmuir–Blodgett technique over the last decade. The large-area, self-organized pattern emerges spontaneously when Langmuir monolayers of L-α-dipalmitoylphosphatidylcholine (DPPC) are transferred onto solid substrates under the right parameters. The obtained patterns can be fixated by chemical modifications, opening up various routes for topographical and/or different chemical contrasts that could be applied in such diverse applications as site-specific immobilization of proteins, cell culture studies, replica patterns, or guidance of small organic molecules for organic electronics. We also briefly discuss several models that were proposed for understanding the pattern emergence by different theoretical groups.
