Front Cover : In article number 2000520 by Myungeun Seo, Wonhee Lee, and co‐workers, a cross‐coupling reaction is utilized for polymer surface modification. Poly(chloro‐p‐xylylene) (parylene C) is used as a substrate in Pd‐catalyzed Buchwald–Hartwig amination to install primary amine groups. Parylene films with a microscale surface topography can be successfully modified and chemically bonded to fabricate transparent and flexible microfluidic channels. The device is compatible with organic solvents and high pressure.
