Effects of Humic and Fulvic Acids on Silver Nanoparticle Stability, Dissolution, and Toxicity.

open access: yesEnvironmental Science and Technology, 2015
The colloidal stability of silver nanoparticles (AgNPs) in natural aquatic environments influences their transport and environmental persistence, while their dissolution to Ag(+) influences their toxicity to organisms. Here, we characterize the colloidal

Quantized conductance observed during sintering of silver nanoparticles by intense terahertz pulses [PDF]

open access: yesApplied Physics Letters, vol. 112, no. 16, p. 163102 (2018), 2018
We show that silver nanoparticles, which are deposited on a terahertz-receiving antenna, can be sintered by intense terahertz pulse irradiation. The conductance of the silver nanoparticles between the antenna electrodes is measured under the terahertz pulse irradiation.

Pharmaceutical aspects of silver nanoparticles [PDF]

open access: yesArtificial Cells, Nanomedicine, and Biotechnology, 2017
Silver nanoparticles are particles in the size ranging between 1 and 100 nm. The two major methods used for synthesis of silver nanoparticle are the physical and chemical methods with the disadvantage that they are expensive and can also have toxicity. Biological method is being used as an expedient alternative, as this approach is environment-friendly

The use of PWHM and Mie methods in estimation of colloidal silver particle size obtained by chemical precipitation with sodium borohydride [PDF]

open access: yesHemijska Industrija, 2019
Unique antibacterial properties of silver have been known since the time of Egyptian pharaohs. With the discovery of antibiotics at the beginning of the twentieth century, silver is mostly pushed out from conventional medicine.

All that is silver is not toxic: silver ion and particle kinetics reveals the role of silver ion aging and dosimetry on the toxicity of silver nanoparticles

open access: yesParticle and Fibre Toxicology, 2018
Background When suspended in cell culture medium, nano-objects composed of soluble metals such as silver can dissolve resulting in ion formation, altered particle properties (e.g. mass, morphology, etc.), and modulated cellular dose.

Flower-shaped nanoparticles improve sensitivity of chemical detection [PDF]

open access: yes, 2013
What you need to know: Raman spectroscopy can be enhanced to be more sensitive in detecting chemicals through the use of nanoparticles with sharper edges and cavities. Silver nanoparticle “flowers” developed at Laurier show the most promising results for
