Objective(s): With the advent of nanotechnology, significant progress has been made in the area of nanoscale materials such as nanosilver (Ag-Nps). These nanoparticles have a wide range of applications and been used for antimicrobial purposes for more than a century. However, little attention has been paid to the toxicity of nanosilver wound dressing. This study was designed to investigate the ...

A common method of silage production in Europe is based on the use cylindrical bales wrapped with polyethylene films. In this study, several modifications composition these films were tested for their impact microorganisms involved ensiling process. Different additives, including nanosilver particles and microcellulose, analyzed upon first stage experiment. second stage, usability recycled as a...

Cytotoxic agents are a main part of therapeutic process against the observed tumors, which lead to some unwished damages, due to drug uptake by normal body cells causing various tissue/organ failures associated with formal administration manners. But nowadays the risk is reduced by new target therapy techniques, of which the observed physical nature of micelles and nanosilver particles, governi...

Differential filtration was used to measure silver (>2 nm) entering and leaving nine sewage treatment plants (STPs). The mean concentration of colloidal (2-450 nm) silver, which includes nanosilver, was found to be 12 ng L(-1) in the influent and 6 ng L(-1) in the effluent. For particulate silver (>450 nm) the mean values were 3.3 μg L(-1) for influent and 0.08 μg L(-1) for effluent. Thus, remo...

Background: Emodin is the main active component of rhubarb, which has demonstrated many beneficial effects against inflammation. Nanosilver is an effective antimicrobial agent. The present study was designed to observe the effects of Emodin combined with silver nanoparticles (E/S) on sepsis protection and related mechanism. Methods: E/S was prepared by loading different concentrations of Emodin...

Nanosilver (nAg) was prepared via Tollens method using dextrin as stabilizer. The morphology, size distribution and average size of the obtained nAg were characterized using Transmission electron microscope (TEM) and Dynamic light scattering (DLS) technique. A kinetic study of toxicity of nAg on Escherichia coli (E. coli) was determined. The obtained results showed that nAg exhibits spheric sha...

Citrus fruits are perishable and considered the most prominent essential crops at local global levels. The world is focused on minimizing fruit postharvest losses, maintaining quality, prolonging its storability marketability. Thus, this study was carried out throughout two successive seasons of 2018 2019 Murcott mandarin fruits, with purpose extending their storage period shelf life by making ...
