Abstract
The cosmetic and the food sectors are deeply involved in the use of nanomaterials and/or nanoparticles. They are added intentionally to products during the production, preparation, treatment, packaging, transport and storage of stuffs to improve specific properties. Because of their several uses, in the light of an awake use of products by consumers, there is the need to study and to understand the NPs properties, and to analyze their impact on environment and on humans. Field Flow fractionation (FFF) techniques are very useful for the characterization of nano- ad micro entities. Centrifugal-FFF, often coupled on-line with specific element detectors, such as ICP-MS, or the flow-FFF are the most common methods used to sort and size NPs. Size, along with shape, morphology and many other physicochemical parameters are, in fact, the principal characteristics, which have to be determined to evaluate the health or/and environmental effects caused by the NPs. This talk will present some examples, chosen in the fields of the cosmetics and food applications, in which the FFF methods show their contribution to the nanoparticle characterization.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
