Plasmachemical Amine Functionalization of Porous Polystyrene Beads: The Importance of Pore Architecture

The functionalization of different types of porous polystyrene microspheres using allylamine plasmas has been explored using a combination of Fmoc derivatization chemistry and cross-sectional Raman microscopy. Higher amine group loadings are obtained for small particles with large internal pore diameters.
