We compare synthesized ZnO hedgehog NPs and commercial ZnO NPs (50 nm and 20 um nominal size) in different concentrations (1 mg/mL and 0.1 mg/mL). Results show that E. coli are more sensitive to the ZnO presence in the cultivation media than S. aureus. We also characterize influence of visible and UV light on the ZnO NP effects.
