AFM studies on dry thickness (A) and roughness (B) of as-deposited PAH/PMAA, as well as GA-crosslinked and DspB-loaded PAH films. (C) Dry thickness of GA-crosslinked PAH films as a function of number of PAH layers before (□ – AFM, △ – ellipsometry) and after DspB loading (■ – AFM, ▲ – ellipsometry). (D) In situ FTIR-ATR data from D2O solutions on a Si ATR crystal. All spectra were taken at pD 7.5: spectrum a – (PAH/PMAA)5; spectrum b – GA-crosslinked (PAH)5 after PMAA release at pD 11.8; spectrum c – DspB-loaded (PAH)5.
