ABSTRACT
The authors compared cytotoxicity of magnetite (Fe3O4) particles in nanometric ranges (10 nm and 50 nm) and micrometer range (1 microm), analyzing changes in cellular subunits of bronchoalveolar lavage in 24 hours after intratracheal application of the particles. Findings are that the nanoparticles are more biologically aggressive than the micrometric particles, but induce more active and effective defensive reaction of alveolar fagocytosis.
