【Abstract】 Wide application of nanomaterial will give researchers, producers and consumers more chance to contact nanomaterial. The nanoparticles can enter human body through several entries. The potential effects of nanoparticles widesly used in the consumer and industrial products caused attention. Nanoscale TiO2 and carbon nanotubes have many potential applications in the industries, commerce and agriculture. Iron oxide nanoparticles are the hot biologic materials on the magnetic resonance imaging (MRI) diagnosis, drug carrier systems and the tumor target therapy. So it is important to study the toxicity of these nanoparticles. The purpose of this review is to provide the toxicological research about iron oxide nanoparticles, nanoscale TiO2 and carbon nanotubes, and offer the problem which should be urgent to be resolved in nanotoxicology.更多还原
