Nanometer-long Ge-imogolite nanotubes cause sustained lung inflammation and fibrosis in rats

摘要

BackgroundGe-imogolites are short aluminogermanate tubular nanomaterials with attractive prospected industrial applications. In view of their nano-scale dimensions and high aspect ratio, they should be examined for their potential to cause respiratory toxicity. Here, we evaluated the respiratory biopersistence and lung toxicity of 2 samples of nanometer-long Ge-imogolites.
