A nanosilver composite plant medium with a good antimicrobial capability was successfully prepared via a two-step method in this work. First, nanosilver particles were prepared in a silver nitrate (AgNO3) solution by using D-glucose as a reduction reagent at room temperature. The effect of AgNO3 concentration levels on the size of the nanosilver particles was investigated. The sedimentation act...

Nanosilver particles are used in various clinical settings because of their antibacterial properties. However, their safety evaluation when used for gynaecological disorders has not been established. Nanosilver particles were administrated in the vagina of New Zealand rabbits, and the pathological appearance of the surrounding tissue was examined by hematoxylin-eosin staining and transmission e...

BACKGROUND The objective of this study was to determine whether the addition of microsilver or nanosilver particles to an orthodontic primer affects shear bond strength (SBS) and bracket/adhesive failure. METHODS Bovine incisors were randomly divided into six groups with 16 specimens in each: In group 1 (control), brackets were bonded with Transbond™ XT primer. In the experimental groups, mic...

background: nanosilver particles are among the potentially candidates for modulating the redox status and changing the growth, performance and quality of plants because of their physicochemical characteristics.   objective: this study was carried out to elucidate the potential effects of nanosilver particles application on variations of photosynthetic pigments (chlorophyll and carotenoids) and ...

We have systematically examined the effects of chitosan film or chitosan in combination with nanometal particles (nanogold or nanosilver particles) on the growth of Schwann cells (S16) and DRG neurons (50B 11). Our results strongly suggest chitosan and chitosan in combination with nanogold particles had no effects on the growth kinetics of Schwann cells but had slightly slowed those of DRG neur...

Nanosilver applications have been implicated in paint, plastic, textile and medical industries. Nanosilver particles absorb sweat and in turn avoid pungent smell of feet. The present study aims to determine the antibacterial activity of Ag-coated different sock fabrics and comparing their efficacy in reducing foot-borne resident bacteria. Synthesize of nanosilver particles was performed in vari...

Nanosilver particles are present in consumer and health care products. Their effects on human microsomal cytochrome P450 (P450) activities and induction in luciferase reporter-engineered Caco-2 (MDR1.C) and HepG2 (DPX2 and 1A2DRE) cells have been investigated. The LD(50) values were ∼ 4 μg silver/ml for HepG2 and 5 μg/ml for Caco-2 cells. At silver concentrations that showed no decreased cell v...

Silver ions are a strong antiseptic with a broad spectrum. Treatment of textiles and leather with nanosilver particles is a new idea for real clean wear. The nanometer-size particles have a large specific surface resulting in the release of silver ions in antiseptic concentration. One way to investigate nanosilver treated leather is the intrinsic fluorescence of organic material. This fluoresce...

The plasmonic properties of noble metal nanoparticles facilitate their use in novel in-vivo bio-applications such as targeted drug delivery and cancer cell therapy. Nanosilver is best suited for such applications as it has the lowest plasmonic losses among all such materials in the UVvisible spectrum. Its toxicity, however, can destroy the surrounding healthy tissue and thus, hinders its safe e...
