Communication: Laterally structured ultrathin polymer films attached t
o solid surfaces can be obtained using photolithographic techniques de
veloped for electronic device fabrication. The Figure shows a surface
plasmon (SP) microscopy image of a structured polystyrene (PS) film of
21.5 nm thickness prepared by photopolymerization. The authors report
a strong adhesion of the polymer films to the substrate due to covale
nt linking.
