Cross‐linked polypeptide‐based films are fabricated via a novel and robust method employing surface‐initiated ring opening polymerization of α ‐amino acid N ‐carboxyanhydrides (NCA‐ROP). The judicious combination of amine‐based hyperbranched macroinitiators and benzyl ester‐protected NCA derivatives promotes network formation by cross‐chain terminations, which allows the formation of stable cross‐linked peptide‐based capsules in a one‐pot system.
