silver salts and nanosilver (ns) are the common antimicrobial used in the treatment of chronic wounds, so they are important to assess their dermal toxicity. therefore, in this study, the possible dermal toxicity of ns particles and silver nitrate (agno3), was tested by determining the serum level of transforming growth factor-β1(tgf-β1) and study on of mouse skin tissue. in this study, 30 balb...

introduction: biocompatibility and antimicrobial activity of endodontic materials are of utmost importance. considering the extensive applications of mineral trioxide aggregate (mta) in dentistry and antimicrobial properties of silver nanoparticles, this study aimed to evaluate the subcutaneous inflammatory reaction of rat connective tissues to white mta with and without nanosilver (ns) particl...

BACKGROUND AND THE PURPOSE OF THE STUDY The most prominent nanoparticles for medical uses are nanosilver particles which are famous for their high anti-microbial activity. Silver ion has been known as a metal ion that exhibit anti-mold, anti-microbial and anti-algal properties for a long time. In particular, it is widely used as silver nitrate aqueous solution which has disinfecting and sterili...

Effects of alfalfa-intercropping and nanosilver-impregnation were studied here on the specific gas permeability of 10-year old Populus nigra var. betulifolia. Specimens were impregnated with a 200 ppm aqueous dispersion of silver nanoparticles under 250 kPa pressure; the results were then compared with the un-impregnated specimens. The size range of silver nanoparticles was 10 to 80 nm. After t...

This study analyzed the growth and biochemical responses of six bacterial colonies isolated from the mucus of the estuarine polychaeta Laeonereis acuta (Nereididae) after exposure to a water suspension of fullerene (nC60) and nanosilver (nAg) separately (0.01; 0.10; and 1.00 mg/L) and together (0.01; 0.10; and 1.00 mg/L of nanosilver and 1.00 mg/L of fullerene added to each nAg concentration). ...

OBJECTIVE Nanotechnology focuses on materials having at least one dimension of less than 100 nanometers. Nanomaterials such as Nanosilver (NS) have unique physical and chemical properties such as size, shape, surface charge. NS particles are thought to in- duce neuronal degeneration and necrosis in the brain. It has been reported that NS parti- cles generate free radicals and oxidative stress w...

In the present study, fabrication and characterization of compound composite nanofibers of Polyvinyl Alcohol (PVA) with nano silver and Polyamide 6 (PA6) are demonstrated. Compound composite fibers with core-shell structure were made using co-axial electrospinning method. The shell was made up of nano silver (Ag) impregnated PVA while PA6 was the core material. These compound composite nanofibe...

Silver nanoparticles are added to a variety of textiles and home goods as an antimicrobial. Although silver has been used safely for centuries, some question whether the rapid expansion of new exposure sources to nanosilver could have adverse consequences.
