Figure 9.

Plot showing the quantified metabolic activity of C. albicans associated with the surfaces (left) of bare catheter tubes and triclosan-loaded SLIPS-coated catheter tubes and (right) the metabolic activity of planktonic cells growing in the surrounding intraluminal medium; metabolic activities were quantified using an XTT assay; all data are normalized with respect to the metabolic activities measured for experiments using bare catheter tubes. Substrates were incubated with C. albicans inoculum for 4 hours, and the surfaces and remaining cell suspensions were quantified separately (see text). Error bars represent standard deviation.
