Micropatterning and nanopatterning with polymeric materials for advanced biointerface‐controlled systems.

Micropatterning and nanopatterning with polymers has become a core technology for many industrially relevant areas and is also recognized as an enabling technology for research and development in many fields ranging from photonics to the biomedical field and beyond. In this review, established key lithographic techniques for patterning and structuring polymeric materials on micrometer and nanometer length scales are discussed and complemented by more recently developed approaches that either rely on polymers to fabricate functional microstructures and nanostructures or form micropatterned and nanopatterned polymers for specific applications with a particular focus on biointerface‐controlled systems. © 2019 Society of Chemical Industry [ABSTRACT FROM AUTHOR]
