Intrinsic toxicity

What are intrinsic toxicity factors?

The intrinsic toxicity of nanoparticles depends on the physical and chemical parameters:


Physical parameter influence.

A particle size or fiber decrease facilitates their penetration into the organsim, the transition from one system (digestive, pulmonary, nervous ) to another and their penetration into cells. Particles may reach distant body parts passing through barriers. The size also determines the place of deposit of nano-objects.
