Fig. 2. Dose-response for INH alone or cis-[Ru(bpy)2(INH)2]2+ (1) when incubated with the 3 classes of bacteria (a) Gram-negative E. coli, (b) Gram-positive B. subtilis, (c) M. smegmatis and (d) normal human lung fibroblast cell line MRC-5 in the dark (gray bars) or photoirradiated (blue bars) using the 96-array blue LED (λ irr = 465 nm, 20 mW cm–2) for various times at 298 K. The survival at each photoirradiation timepoint was compared to the light control in the absence of the complex, while the survival for the complex in the dark was compared to the dark control in the absence of complex. p values were calculated by comparing the light samples to the dark samples and are labelled as follows, p ≤ 0.05 = *, p ≤ 0.01 = **.
