Toxicity of silver nanoparticles—Nanoparticle or silver ion?

Toxicology Letters, 2012
The 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, 2013
Noble-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, 2014
Metal 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

Silver nanoparticles in dentistry

Dental Materials, 2017
Silver 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 ...

Remobilisation of silver and silver sulphide nanoparticles in soils

Environmental Pollution, 2014
Manufactured nanoparticles (NPs) present in consumer products could enter soils through re-use of biosolids. Among these NPs are those based on silver (Ag), which are found sulphidised (e.g. silver sulphide, Ag2S) in biosolids. Herein, our aim was to examine the release of retained Ag(0) and Ag2S NPs in soils and biosolids as facilitated by ...

Biosynthesized silver nanoparticles and their genotoxicity

Journal of Biochemical and Molecular Toxicology, 2019
AbstractThe human‐pathogenic bacteria have become highly resistant to conventional antibiotics; for this reason, a new biosynthesized nanomaterial might be a solution. The culture filtrate of two isolates of Fusarium oxysporum (14, 17) was used in the biosynthesis of nanosilver (AgNPs).

Mycosynthesis of silver nanoparticles: a review

BioMetals, 2022
Metallic nanoparticles currently show multiple applications in the industrial, clinical and environmental fields due to their particular physicochemical characteristics. Conventional approaches for the synthesis of silver nanoparticles (AgNPs) are based on physicochemical processes which, although they show advantages such as high productivity and good
