Instantaneous and creep indentations of Pseudomonas aeruginosa biofilms at SFTV—variable-push and -pull experiments. Means and standard errors of data are shown from two independent experiments per sample. Each experiment consists of 10 replicate force plots under standard loading force (10 nN), contact time (1 s), and ramp velocity (2 μm/s). Indentation data were extracted from the resulting creep curves. PAO1-ebf: PAO1 early biofilm; wapR-ebf: wapR early biofilm; PAO1-mbf: PAO1 mature biofilm; wapR-mbf: wapR mature biofilm.
