Figure 1: MPO measured in the liver tissue following 6 hr exposure to 100 μl in 128 μg/ml of the panel of NMs (NM 110–ZnO uncoated; NM 111–ZnO coated; NM 300–Ag; NM 400–MWCNT; NM 402-MWCNT; NRCWE 002–positively charged TiO2. A positive control of LPS (50 μl-100 μg/ml) was also employed. The negative control is representative of animals injected with 100 μl of PBS. (n=3 ± SEM) *P <0.05, **P<0.005 compared to negative control.
