Figure 7.

Normalized growth inhibition of bacteria by UV (λ_exposure = 365 nm, pH = 3.0) when exposed with brominated carbon nanodot (“BrCND”) or carbon nanodot (“CND”) solutions of varying absorption intensities (due to sample concentration differences). Bacterial strains include A) Staphylococcus aureus (2 J•cm⁻²) and B) Escherichia coli (1 J•cm⁻²). Growth inhibition values were normalized against the “0” nanodot condition (*) = 1. Error is propagated from the standard deviation of n ≥ 3 trials.
