Exposure and use of nanoparticles are widely called into question by recent awareness of the existence of poorly understood potential risks. These nanoparticles have properties and behavior different from other particles because of their very small size. They are characterized and classified according to particular behaviors and new parameters specific to them. However, fine particles of larger size, nanoparticles, are known for their toxicity towards the environment and the human body. Due to their small size, they can easily penetrate the body by crossing barriers, as well as disperse throughout the environment and reach fauna, flora, and humans.
