Body distribution of inhaled fluorescent magnetic nanoparticles in mice.

To address the questions about the potential harmful effects of nanoparticles for workers, this article studied the body distribution of inhaled nanoparticles in mice using approximately fifty nano-meter sized fluorescent magnetic nanoparticles. These particles were distributed in various organs including the liver, testis, spleen, lung, and brain. The authors conclude the to predict and prevent the potential toxicity of nanomaterials, extensive studies should be performed under different routes of exposure with different sizes and shapes of nanomaterials.
