Figure 3

Shown are sustained diameter changes (mean±SEM) with 30 s continuous exposure via micropipette to Fe-SWCNT or Gd-SWCNT coated with 0.1% PEG-DSPE that were aggregated (hamster N=14; mouse N=7) or non-aggregated (monodispersed; hamster N=4; mouse=4) in hamster cheek pouch or mouse cremaster muscle. The x-axis gives the concentration in the micropipette; kindly refer to the Methods for exposure dose per arteriole. The dose of 0 μg/ml SWCNT contains only PEG-DSPE at 0.1%. Two classifications of arterioles were observed: arcade arterioles (A); terminal arterioles (B). The legend in (A) applies to both (A) and (B). *dilation in each group significant at that dose; **constriction in each group significant at that dose; p<0.05.
