Abstract Advanced treated municipal wastewater is an important alternative water source for agricultural irrigation. However, the possible persistence of chemical and microbiological contaminants in these waters raise potential safety concerns with regard to reusing food crop Two low-cost environmentally-friendly filter media, biochar (BC) zero-valent iron (ZVI), have attracted great interest t...

Silver nanoparticles (Ag NPs) have been widely used as new potent antimicrobial agents in cosmetic and hygienic products. Present study compares the tissue levels of Ag NPs in different organs of Guiana Pigs quantitatively after dermal application and analysis the morphological changes and pathological abnormalities on the basis of the Ag NPs tissue levels. Before toxicological assessments,the...

The aim of the work: to study antimicrobial efficacy xenografts saturated by silver nanoparticles, suggest their application in treatment burned wounds.
 Materials and Methods. with nanocrystals was investigated vitro diffusion into agar, a liquid nutrient medium studying adhesive activity using test cultures: Staphylococcus aureus АТСС 6538, Escherichia coli 25922, Pseudomonas aeruginosa ...

Betulin, being a pentacyclic triterpene alcohol and an extractive from birch bark, along with its oxo-derivatives, has broad range of physiological properties interest for synthesis pharmaceuticals. Instead oxidizing betulin strong toxic agents the present study shows possibility using liquid-phase oxidation air over supported Ag NPs catalysts as alternative method oxo-derivatives. Based on cat...

BACKGROUND/PURPOSE To investigate the effect of nanosilver particles in solution stabilized in a matrix of sodium alginate on the growth and development of pathogenic bacteria such as Staphylococcus aureus, Enterococcus faecalis, Escherichia coli, Proteus vulgaris, Enterobacter cloacae, the antibiotic-resistant strain of Pseudomonas aeruginosa, the yeast-like fungus Candida albicans, and the lu...

The addition of an antibacterial agent to dental implants may provide the opportunity to decrease the percentage of implant failures due to peri-implantitis. For this purpose, in this study, the potential efficacy of nanosilver-doped titanium biomaterials was determined. Titanium disks were incorporated with silver nanoparticles over different time periods by Tollens reaction, which is consider...

Silver is a strong antibiotic that is increasingly incorporated into consumer products as a bulk, salt, or nanosilver, thus potentially causing side-effects related to human exposure. However, the fate and behavior of (nano)silver in the human body is presently not well understood. In order to aggregate the existing experimental information, a physiologically based pharmacokinetic model (PBPK) ...

Aim. To assess the effectiveness of nanosilver gel (NSG) in comparison to chlorhexidine gluconate (CHX) and camphorated phenol (CP) against Enterococcus faecalis (E.f) biofilm. Methods and Materials. Two tests were done, methyl thiazolyl tetrazolium (MTT) assay and confocal laser scanning microscopy (CLSM) analysis, to determine the effectiveness of NSG, CHX, and CP on E.f biofilm. Polystyrene ...

The emergence of nanosilver (silver in nanoscale shapes and their assemblies) benefits the landscape modern healthcare; however, this brings about concerns over its safety issues associated with an ultrasmall size high mobility. By reviewing previous reporting details synthesis characterization biological responses, a gap between materials biomedical uses is characterized by insufficient unders...

Silver nanoparticles have proved to possess significant antibacterial properties. Nanosilver produced by electrochemical reduction stabilized by cellulose derivatives, has been evaluated by European standards (CEN TC 216) in order to find out whether they could be applied in food, industrial, domestic and institutional areas as a suitable disinfectant. Moreover, bactericidal activity of nanosil...
