A Tandem Chemical Vapor Deposition Platform for the Solvent‐Free Synthesis of Polypeptide Architectures

open access: yesChemistry – A European Journal, EarlyView.
A solvent‐free, two‐step chemical vapor polymerization enables efficient, substrate‐independent synthesis of surface‐attached polypeptide films. Initiator deposition via CVD is followed by NCA ring‐opening polymerization. Characterization confirms film formation and functionalization, allowing precise micropatterning and bioactive surface design for ...
