Fig. 6From: Differential pulmonary effects of CoO and La2O3 metal oxide nanoparticle responses during aerosolized inhalation in miceTransformation of La2O3 nanoparticles in phagolysosomal simulated fluid (PSF). a TEM images and b XRD spectra of La2O3 nanoparticles after PSF exposure. La2O3 nanoparticles were suspended in H2O or PSF at 50 μg/mL and incubated at 37 °C for 24 h. After washing in H2O, the morphological and crystal structure changes in La2O3 nanoparticles were examined by TEM and XRD, respectivelyBack to article page
