Atomic force microscopy (AFM) images of compound 8 thin films prepared by dip-coating. Images were taken in tapping mode in air. (a) Thin film on mica, DMSO solution, (b) thin film on silicon wafer, DMSO solution and (c) thin film on mica, H2O/DMSO solution (5.9% DMSO). (d) Self-assembled fibres on mica, H2O/DMSO solution (5.9% DMSO), imaged in tapping mode in air, (e) E. coli flocs observed in liquid using PeakForce QNM mode, (f) E. coli flocs imaged by scanning electron microscopy (SEM).
