Front Cover: A new approach to prepare free-standing biodegradable nanopillar arrays on flexible substrates is developed by using plasma etching with block copolymer micelles encapsulating Au nanoparticles as an etching mask. This method can offer a feasible route to create vertically-aligned nanostructures of various materials with dimensional controllability. This is reported by Gyeong Won Lee, Seunghyun Lee, Jang Hwan Kim, Sang-Gu Yim, Jooyeon Ryu, Eunji Lee, Jaebeom Lee, Seong Il Yoo, and Seung Yun Yang in article number 1600361.
