Abstract

Increased motivation for environmental monitoring requires robust and reliable sensors. The present work aims at increasing the service time of optical sensors immersed in riverine waters by decreasing the development of biofouling on their surface. In this aim, nanocomposite coatings composed of metallic silver nanoparticles embedded in an amorphous alumina are co-deposited on sensor glass windows by chemical vapor deposition. Immersion for one week in the Saulx river, France, revealed a threefold decrease of biofouling on their surface compared with untreated glass surfaces while maintaining transparency. Such coatings can be considered as part of integrated tools, including for example mechanical cleaning, to reduce the maintenance of optical sensors immerged in riverine waters.
