Brushing the surface: Structured polymer brushes are readily prepared by site-selective immobilization of initiators in a self-assembly process by Langmuir–Blodgett lithography with subsequent polymerization. The AFM images show a DPPC/alkoxy amine LB film before and after surface-initiated controlled nitroxide-mediated radical polymerization. Large surface areas (several cm2) can readily be structured with this method.
