Nanophase‐separated poly(acrylic acid)/poly(ethylene oxide) plasma polymers for the spatially localized attachment of biomolecules

Carboxyl‐enriched nanoparticles are produced by the plasma polymerization of acrylic acid (ppAA NPs), whereas plasma‐assisted vapor‐phase deposition is used to prepare thin films of poly(ethylene oxide) (ppPEO). Sequential depositions generate phase‐separated coatings. The ppAA NPs are found to be in a glassy state, whereas thin films of ppPEO are found to be in a rubbery state. When immersed into a solution of lysozymes, the ppPEO absorbs...
