Treatment of P. aeruginosa biofilms with COS and COS-NO. (A) Biofilm viability following exposure to COS or COS-NO for 18 h. While COS did not fully eradicate biofilms, the MBEC of COS-NO was 4 mg ml−1 (NO dose of 3.1 ± 0.4 μmol). (B) MSDτ=0.83s of biofilms treated with COS and COS-NO. The MSDτ=0.83s of untreated biofilms is indicated as a horizontal line. Note the logarithmic scale of the y-axis. (C) The MSD values of biofilms treated with COS and (D) COS-NO. All MSD were determined by tracking particles in 15 distinct areas of 3 separate biofilms and are plotted as ensemble average MSD ± SEM. Diffusion coefficients of viscous solutions (α = 1) and elastic solids (α = 0) are superimposed on MSD plots for reference.
