BACKGROUND Bacterial resistance against the classic antibiotics is posing an increasing challenge for the prevention and treatment of infections in health care environments. The introduction of antimicrobial nanocoatings with active ingredients provides alternative measures for active killing of microorganisms, through a preventive hygiene approach. PURPOSE The purpose of this study was to in...

Biosynthesis of nanosilver by using sweet orange (C. sinensis) as a bioreductor has shown nanosized results. In this research, the effect volume variation juice and peel extract combination toward characteristics antibacterial activity synthesized will be studied. Solution AgNO3 1 mM was mixed with – ratios (v/v), 3:0; 1.5:1.5; 1:2; 0.5:2.5 0:3 at 60˚C for 45 minutes. The color change solution ...

this study was conducted to compare the effect of various commercial in-feed disinfectants on layer performance, intestinal microflora, and egg cholesterol. one hundred and eight layer hens (lsl, 24 wks of age) were divided into six groups consisting: control, formaycin-200 ppm, formalin-200 ppm, and nanosilver in feed-15 ppm or drinking water-7.5 ppm. there were no differences between experime...

Nanosilver (10−9 m) refers to particles comprising 20–15,000 silver atoms, exhibiting high stability and specific surface area. At present, nanosilver has been used in agricultural cultivation production. This study examined the effects of on growth development rice root systems. Study results showed that fresh weight belowground organs length both increased significantly by 5% 25%, respectivel...

Background & Aims: Nanosilver-based paint is a new technology with antimicrobial and antifungal characteristics. These characteristics were investigated in this study with regard to fungal contamination in hospitals. Method: Regarding hospitalization of transplant patients and their sensitivity to hospital infections, two similar rooms were selected in nephrology ward. One of them was paint...

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...

background and aim: bacterial elimination from root canal system is one of the aims in endodontic treatments, so the addition of antibiotics to sealers can increase their antimicrobial efficacy, as in this study we are determining the in-vitro antimicrobial effect of ah26 and ah plus sealers mixed with amoxicillin, triple antibiotic pastes and nanosilver on enterococcus faecalis. materials and ...

introduction: favorable apical seal of root filling materials is a crucial factor for a successful root canal treatment. the aim of this in vitro study was to compare bacterial and dye microleakage of two root canal filling materials including standard gutta-percha and nanosilver coated gutta-percha, and to evaluate the agreement between results of these two methods . materials & methods: fifty...
