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:

Uptake, translocation, and transformation of silver nanoparticles in plants
TL;DR: In this article , the plant uptake of silver nanoparticles (AgNPs) that occurred in soil systems and the in planta fate of AgNPs were reviewed, and the authors concluded that the uptake of Silver NPs was beneficial for plant growth.

Multistep Method to Extract Moderately Soluble Copper Oxide Nanoparticles from Soil for Quantification and Characterization.
Garret D. Bland,Gregory V. Lowry +1 more
TL;DR: This procedure is the first to effectively extract soluble NPs from soil and experimentally separate them from their dissolved fraction and can be applied to other moderately soluble metal containing natural, incidental, or engineered NPs in soil.

Simple Method for the Extraction and Determination of Ti-, Zn-, Ag-, and Au-Containing Nanoparticles in Sediments Using Single-Particle Inductively Coupled Plasma Mass Spectrometry.
TL;DR: In this article, a single-particle inductively coupled plasma mass spectrometry (SP-ICP-MS) technique was used for separating and analyzing metal-containing nanoparticles in sediment samples.

Journal ArticleDOI
A new test system for unraveling the effects of soil components on the uptake and toxicity of silver nanoparticles (NM-300K) in simulated pore water.
TL;DR: A mechanistic view of exposure and uptake of AgNP (and other substances) by F. candida from soil pore water is provided and a strong correlation existed between the concentration of nano silver and immobilization; for ionic silver this was not the case.

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.
