Five assays to study nanoparticle reactive oxygen species generation and effects on bacterial membrane integrity, membrane potential, and electron transport chain activity are assessed. A detailed quantitative assessment of nanoscale TiO2, CeO2, and ZnO interferences with assay reagents and function are included, in the context of a general scheme to test for nanoparticle interferences with fluorescence- and absorbance-based assays.
