Coatings: Dynamic Fluoroalkyl Polyethylene Glycol Co-Polymers: A New Strategy for Reducing Protein Adhesion in Lab-on-a-Chip Devices (Adv. Funct. Mater. 4/2015).

An antifouling coating that improves digital microfluidic device lifetime up to 5.5‐fold relative to the state of the art is described by A. R. Wheeler and team on page 506. The material is dynamic: under standard conditions, the surface is flat and fluorinated; upon applying an electrical potential, the surface becomes activated, forming nanometer‐sized fluoropegylated structures that resist protein adhesion.
