a LR vs [Cu] leached. The EPA-prescribed 3-LR, corresponding to >99.9% reduction in bacterial colony counts, is marked with a black line. The blue and pink shaded regions correspond to the [Cu] range above and below which a 3-LR was observed, respectively. *The comparison between LR and [Cu] leached assumes that the majority of the ions are held in the liquid phase and not consumed by the microorganisms i.e., rate of Cu dissolution due to the PBS >> rate of consumption of Cu due to the presence of microorganisms. b Transmission spectra of representative TANCSs. For both graphs, the circle and square markers represent TANCSs from Sets A and B, respectively. Inset of (b) shows photographs of Set A and Set B after mock testing where the marked central region marked shows the testing area of 1 × 1 in.2.
