Toxicity of silver nanoparticles—Nanoparticle or silver ion?
Toxicology Letters, 2012The toxicity of silver nanoparticles (AgNPs) has been shown in many publications. Here we investigated to which degree the silver ion fraction of AgNP suspensions, contribute to the toxicity of AgNPs in A549 lung cells. Cell viability assays revealed that AgNP suspensions were more toxic when the initial silver ion fraction was higher.

Ultrastable silver nanoparticles
Nature, 2013Noble-metal nanoparticles have had a substantial impact across a diverse range of fields, including catalysis, sensing, photochemistry, optoelectronics, energy conversion and medicine. Although silver has very desirable physical properties, good relative abundance and low cost, gold nanoparticles have been widely favoured owing to their proved ...

Biosynthesis of Silver Nanoparticles
Journal of Nanoscience and Nanotechnology, 2014Metal nanoparticles have unique optical, electronic, and catalytic properties. There exist well-defined physical and chemical processes for their preparation. Those processes often yield small quantities of nanoparticles having undesired morphology, and involve high temperatures for the reaction and the use of hazardous chemicals. Relatively, the older

Dithiocarbamate-Capped Silver Nanoparticles
The Journal of Physical Chemistry B, 2006Nanometer-sized silver particles were synthesized by using didecylamine dithiocarbamates as the protecting ligands. With control of the initial ligand-metal feed ratios, the core diameter of the resulting particles was found to vary from about 5 to 2.5 nm, as determined by transmission electron microscopic measurements.

Solvent-Adaptable Silver Nanoparticles
Langmuir, 2005A simple and efficient way of obtaining silver nanoparticles that are dispersible both in organic and in aqueous solvents using a single capping agent is described. The silver nanoparticles are initially prepared in water in the presence of aerosol OT [sodium bis(2-ethylhexyl)-sulfosuccinate, AOT].

Silver nanoparticles in dentistry
Dental Materials, 2017Silver nanoparticles (AgNPs) have been extensively studied for their antimicrobial properties, which provide an extensive applicability in dentistry. Because of this increasing interest in AgNPs, the objective of this paper was to review their use in nanocomposites; implant coatings; pre-formulation with antimicrobial activity against cariogenic ...

Temporal fluctuations in the Raman spectrum from molecules adsorbed to noble metal colloids (i.e., “blinking”) has been viewed as a single molecule signature. It is demonstrated here that silver colloids exhibit blinking that is independent of the nature of the adsorbate.
