From: The effect of titanium dioxide nanoparticles on pulmonary surfactant function and ultrastructure
Surface activity evaluated with the pulsating bubble surfactometer. A) Adsorption surface tension (γads) after incubation with TiO2 nanosized particles (NSP) at a static bubble condition. B) Influence of TiO2 microsized particles (MSP) on γads C) Influence of TiO2 NSP on surface tension at minimal bubble size (γmin) during pulsation D) γmin after incubation with TiO2 MSP. Values are given as means of at least 4 experiments ± SEM. ** indicates p values < 0.01 compared with the control at 0 μg/ml particle concentration.
