Le comité de pilotage du C'Nano national a l'immense plaisir de vous annoncer la création d'une unité propre de service par le CNRS (UPS) pour capitaliser l’expérience accumulée par le réseau et pérenniser sa structuration nationale et régionale.
Depuis plus de dix ans, le C’Nano avec ses 6 centres de compétence régionaux (C’Nano Grand-Est, Auvergne-Rhône-Alpes, Provence-Alpes-Côte d’Azur, Grand Sud-Ouest, Nord-Ouest et Ile-de-France) entreprend des actions de promotion de la recherche en nanosciences et en nanotechnologies et œuvre pour établir des partenariats d’échanges avec les communautés scientifiques internationales. C'est pour nous l’opportunité d'un renouveau qui sera marqué par l’organisation de journées nationales annuelles dont la première édition se tiendra à Lyon les 5,6 et 7 décembre prochain (save the date).

Addition of titanium dioxide (TiO2) (nano)particles into photocatalytic paints represents a promising alternative aiming to mineralize gaseous pollutants, such as volatile organic compounds (VOCs) into innocuous species (H2O and CO2). Despite important industrial and economic benefits, some concerns were raised regarding the risks associated with nano-objects and their human and environmental impacts.
Silver nanoparticles (Ag-NPs) are widely used as biocides, leading to contamination of the environment and possible adverse effects on humans. Recent studies revealed that the cellular response to acute exposure to Ag-NPs differs from the response to chronic exposure, although we currently lack systematic studies comparing responses to different dosing regimens.
Indoor aquatic mesocosms are increasingly used in nanosafety to assess the behavior, fate, and impacts of engineered nanomaterials (ENMs) in aquatic environments using relevant exposure scenarios.
In recent years, nanotechnologies have led to undeniable progress in any domains, such as electronics, materials and medicine. Despite the benefits of such a technology, a careful assessment of the potential risks for Human and Environmental health have to be studied. Assessing exposure and hazard to nanomaterials is a major challenge in the field of environmental sciences.
