摘要: Nowadays more than thousands of different nanoparticles are known, though no well-defined guidelines to
evaluate their potential toxicity and to control their exposure are fully provided. The way of entry of nanoparticles together
with their specificities such as chemistry, chemical composition, size, shape or morphology, surface charge and
area can influence their biological activities and effects. A specific property may give rise to either a safe particle or to a
dangerous one. The small size allows nanoparticles to enter the body by crossing several barriers, to pass into the blood
stream and lymphatic system from where they can reach organs and tissues and strictly interact with biological structures,
thus damaging their normal functions in different ways. This review provides a summary of what is known on the toxicology
related to the specificity of nanoparticles, both as technological tools or ambient pollutants. The aim is to highlight
their potential hazard and to provide a balanced update on all the important questions and directions that should be focused
in the near future.
