Abstract A novel approach to producing improved bio‐interfaces by combining continuous wave (CW) and pulsed plasma polymerization (PP) modes is reported. This approach has enabled the generation of stable interfaces with a higher density of primary amine functionality on metal, ceramic and semiconductor surfaces. Heptylamine (HA) was used as the amine‐precursor. In this new design, a thin CW PPHA layer is introduced to provide strong cross‐linking and attachment to the metal or semiconductor surfaces and to provide a good foundation for better bonding a pulsed PPHA layer with high retention of functional groups. The combined mode provides the pulsed mode advantage of a 3‐fold higher density of primary amines, while retaining much of the markedly higher stability in aqueous solutions of the continuous mode. magnified image
