Figure 2.

Representative time-resolved SHS signal collected during bacterial uptake of MG following (a) 0 h or (b) 1 h exposure to 0 (black), 25 (green), 75 (blue), or 150 μM (purple) AZM. SHS intensities have been normalized to the CM transport peak. Dashed lines represent best fit results. Fit deduced rate constants corresponding to (c) adsorption onto the outer surface of the CM and (d) transport across the CM, as a function of AZM concentration. The relative fraction of fast (blue) and slow (red) transport are annotated above the corresponding markers in (d). Error bars depict standard deviation of the rates from minimally n = 3 trials for each AZM concentration.
