ABSTRACT
It is well established (from which the general interest arises!) that nanomaterials (NM) display properties and behavior that can be very different compared to the corresponding bulk materials of the same chemical composition. Size, shape, and surface state are properties accounting for most of their differences (1,2). The physical and chemical characterization of NM are important steps in toxicological and ecotoxicological studies in order to correctly evaluate and assess their potential exposure routes, toxicity, and related risk.
