Nanotoxicology

Nanotoxicology is study of the nature and mechanism of toxic effects of nanoparticles on living organisms and other biological systems. It also deals with the quantitative assessment of the severity and occurrence of nanotoxic effects relative to the exposure of the organisms. Human exposure routes are mainly mediated through inhalation, dermal, oral intake or by injection. The small particle size and the shape of nanomaterial allows to uptake into blood and lymph circulation and circulation to tissues in the body that normally are protected by barriers, such as the brain by penetration of the blood-brain-barrier (BBB).
