Preparation, Properties, and Bioapplications of Block Copolymer Nanopatterns

Abstract

AbstractBlock copolymer (BCP) self‐assembly has emerged as a feasible method for large‐scale fabrication with remarkable precision – features that are not common for most of the nanofabrication techniques. In this review, recent advancements in the molecular design of BCP along with state‐of‐the‐art processing methodologies based on microphase separation alone or its combination with different lithography methods are presented. Furthermore, the bioapplications of the generated nanopatterns in the development of protein arrays, cell‐selective surfaces, and antibacterial coatings are explored. Finally, the current challenges in the field are outlined and the potential breakthroughs that can be achieved by adopting BCP approaches already applied in the fabrication of electronic devices are discussed.
