(A) Time-lapse height images obtained by real-time AFM capturing the changes in film thickness and morphology of LbL film 2 in 10 mM DTT. The images were captured by the contact mode in liquid. The scan size is 20 μm; Z range is 450 nm; and scale bar is 4 μm. (B) LbL film 2 thickness variation as a function of degradation time in DTT solution.
Abbreviations: AFM, atomic force microscopy; LbL, layer-by-layer; DTT, dithiothreitol.
