Interaction of Freshwater Diatom with Gold Nanoparticles : Adsorption , Assimilation , and Stabilization by Cell Exometabolites

The rising concern about the potential toxicity of synthetic gold nanoparticles (AuNPs) in aquatic environments requires a rigorous estimation of physico-chemical parameters of reactions between AuNPs and major freshwater microorganisms. This study addresses the interaction of 10-nm size, positively charged AuNPs with periphytic freshwater diatoms (Eolimna… (More)
