TLDR
It is suggested that Ag MNP coating does not need to be taken into account to understand fate of AgMNPs applied to soil through biosolids amendment, because pre-incubation with sewage sludge negated these effects.About:

Aging reduces the toxicity of pristine but not sulphidised silver nanoparticles to soil bacteria
Carolin L. Schultz,Joanna Gray,Rudo A. Verweij,Martí Busquets-Fité,Víctor F. Puntes,Víctor F. Puntes,Claus Svendsen,Elma Lahive,Marianne Matzke +8 more
TL;DR: In this paper, two soil bacteria were exposed to Ag ENPs in ISO media (± fulvic acid) and soil pore water extracts with pH 6 and pH 8, and the results showed that aging reduced toxicity in media with organic matter.

Alteration of Crop Yield and Quality of Three Vegetables upon Exposure to Silver Nanoparticles in Sludge-Amended Soil
TL;DR: The impacts of land application of sludge contaminated with silver nanoparticles (Ag NPs) on crop yield and nutritional quality are relatively unknown as discussed by the authors, and the impacts of such sludge contamination on agricultural crops are unknown.

Engineered Nanomaterials for Phytoremediation of Metal/Metalloid-Contaminated Soils: Implications for Plant Physiology
TL;DR: Nanomaterials, including engineered nano-sized iron oxides, manganese oxides and cerium oxides as mentioned in this paper, provide specific affinity for metal/metalloids adsorption and their application is being rapidly extended for environmental management.

High retention of silver sulfide nanoparticles in natural soils
TL;DR: In contrast to Ag2S-NPs, silver nanoparticles (AgNPs) and Ag+ in these soils were less retained and the retention was closely associated with soil properties, which highlights the unique behaviors of Ag2NPs in natural soils.

A study of the nucleation and growth processes in the synthesis of colloidal gold
TL;DR: In this paper, a preliminary survey with the electron microscope of various preparations of colloidal gold, a study was made of the process of nucleation and growth in gold colloids, and it was shown that nucleating agents may be identified with reducing agents which form a mixed polymer with chlorauric ion before the reduction to the nucleus takes place.

Analysis of Macromolecular Polydispersity in Intensity Correlation Spectroscopy: The Method of Cumulants
TL;DR: The first order electric field correlation function of laser light scattered by polydisperse solutions of macromolecules can be written as a sum or distribution of exponentials, with decay rates proportional to the diffusion coefficients of the solute molecules as discussed by the authors.

Modeled Environmental Concentrations of Engineered Nanomaterials (TiO2, ZnO, Ag, CNT, Fullerenes) for Different Regions
TL;DR: The results of this study indicate that risks to aquatic organisms may currently emanate from nano- Ag, nano-TiO(2), and nano-ZnO in sewage treatment effluents for all considered regions and for nano-Ag in surface waters.

Nanoparticle Silver Released into Water from Commercially Available Sock Fabrics
Troy M. Benn,Paul Westerhoff +1 more
TL;DR: Variable leaching rates among sock types suggests that the sock manufacturing process may control the release of silver, and physical separation and ion selective electrode (ISE) analyses suggest that both colloidal and ionic silver leach from the socks.
