Nano toxicology

Nanotoxicology specifically deals with the toxicity of nanomaterials/nanoparticles. The essential aim of nanotoxicological studies is to determine the toxic/unsafe effects of nanoparticles and nanopharmaceuticals on people and environment. Typical nanoparticles which have been widely studied in unique toxicological research are silver (Ag-NPs), gold (Au-NPs), titanium dioxide (TiO2-NPs), cesium dioxide, iron oxide, alumina, zinc oxide (ZnO-NPs), carbon black (CB), and diesel exhausted nanoparticles, in addition to carbon nanotubes, fullerenes, and “nano-C60” (Khalili Fard et al., 2015; Azhdarzadeh et al., 2015). Because of quantum size effects and massive surface area-to-volume ratio, nanomaterials have unique properties, in comparison with their large counterparts. The toxicity of nanoparticles may not be seen with larger debris that encompass the equal material or detail. Nanomaterials, even fabricated from inert factors (such as gold) can come to be particularly active at the nanometer dimensions (Khalili Fard et al., 2015; Azhdarzadeh et al., 2015).
