Fig. 1. (A) A schematic of RGD-comb structure at the polymer-water interface. Adhesion peptides (pink) are tethered to the comb backbone (blue) via short poly(ethylene oxide) side chains (yellow) that protrude into the aqueous phase owing to their favorable interaction with water. (B) Quasi-2D configuration of an RGD-comb island at the polymer-water interface.
