“…3c). This could be explained by a photo-oxidationinduced formation of an intermediate metal oxide phase (Ag 2 O, for example) at the surface of the AgNPs 25,26 . According to equilibrium isotope fractionation rules 19 , the heavy isotope is prone to being concentrated in compounds with a higher oxidation state.…”

“…These transformations are governed by the inherent solubility, reactivity and sorption ability of AgNMs, influenced by physicochemical characteristics such as: size, [175] shape, [26] surface structures, [26] surface chemistry [176] or coatings. [134] However, hybridisation of chemically active AgNMs with a relatively inert gold overcoating can reduce Ag þ dissolution (Fig.…”

“…The chemical reduction of Ag + to form AgNPs stabilized with citrate is a commonly utilized synthesis method designed to make a relatively uniform suspensions of particles in water, typically with a particle diameter near 20 nm [3,4]. These suspensions are employed in studies involving stability, fate and transport as well as in further processing to yield more chemically complex systems.…”

“…The first focuses on the AgNPs and examines their formation and stability in various environments [3][4][5], using the information learned towards predicting likely behavior in applications after incorporation into a material or product. The scientific understanding gained from studying the formation and stability of AgNPs in various environments can be used to provide engineering guidance for the safe storage and handling of AgNP suspensions [4] and for the development of AgNP reference materials [1,5] for instrument calibration or measurement intercomparison.…”
