Fig. 6From: Density of surface charge is a more predictive factor of the toxicity of cationic carbon nanoparticles than zeta potentialAirway inflammation induced by the 6 NPs in mice. Mice received a single lung administration of 100 µg of NPs or saline (CTL), and airway inflammation was assessed 24 h later by counting cells (a) and measuring cytokines (b) in bronchoalveolar lavage fluids. Data are means ± SEM of n = 6 mice. Statistical differences when compared to controls (CTL) were determined by one-way ANOVA followed by the Dunnett’s test. **p < 0.01; ***p < 0.001Back to article page
