nanosilver of nanometer-sized silver (ag+) particles (2-5 nm diam) are used in various applications as an anti-microbial. boric acid (h3bo3) is water soluble (ph=7). boric acid is ethylene synthese inhibitor and reduce ethylene production through reducing the acc synthase and acc oxidase delays senescence of flower. in this study of different concentrations of boric acid and nano-silver was eva...

Despite increasing application of silver nanoparticles (NPs) in industry and consumer products, there is still little known about their potential toxicity, particularly to organisms in aquatic environments. Regarding fast development of the nanotechnology and its diverse applications, is very important having enough data on the probably its side effects on the aquatic body organs. Therefore, pr...

Manufacturers of clothing articles employ nanosilver (n-Ag) as an antimicrobial agent, but the environmental impacts of n-Ag release from commercial products are unknown. The quantity and form of the nanomaterials released from consumer products should be determined to assess the environmental risks of nanotechnology. This paper investigates silver released from commercial clothing (socks) into...

objective: antibacterial properties of silver nanoparticles have recently come into the spotlight in endodontic therapy. this study was conducted aiming at comparing the antimicrobial activity of a new irrigation solution containing nanosilver particles with that of sodium hypochlorite and chlorhexidine against escherichia coli, enterococcus faecalis, pseudomonas aeruginosa and candida albicans...

A cradle-to-grave life cycle assessment (LCA) is performed to compare nanosilver T-shirts with conventional T-shirts with and without biocidal treatment. For nanosilver production and textile incorporation, we investigate two processes: flame spray pyrolysis (FSP) and plasma polymerization with silver co-sputtering (PlaSpu). Prospective environmental impacts due to increased nanosilver T-shirt ...

The influence of ketoconazole and β-CD/ketoconazole on cotton fabric as fungal skincare was previously reported however the impact nanosilver antifungal antibacterial properties same products is unknown. Here, silver NPs were synthesized β-CD/KZ composite then loaded by using a cross-linking agent. nanocomposite treated fabrics analyzed diffenent means such UV–vis, dynamic light scattering, zet...

BACKGROUND Nanosilver particles of which antibacterial and antifungal properties have been shown in various in vitro and in vivo studies are used in many medical and dental fields for the prevention of infection. In this study, it is intended to evaluate the biocompatibility of nanosilver-coated brackets. METHODS Nanosilver coating process was applied to the standard orthodontic brackets by a...

Antibacterial multilayer films containing nanosilver were prepared via layer-by-layer fashion. PET film was aminolyzed with 1,6-hexanediamine to introduce amino groups on PET film surface; chitosan-silver nitrate complex and heparin were alternately deposited onto an aminolyzed PET film surface, and subsequently, the silver ions within the multilayer films were reduced with ascorbic acid to for...

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...
