objectives the aim of this study was to evaluate the stability of antibacterial properties of nanosilver solution during a period of 9 months against streptococcus mutans, staphylococcus aureus and pseudomonas aeruginosa. materials and methods in this in vitro study, the antibacterial effect of serial concentrations of nanosilver solution and amoxicillin antibiotic as control group on the stand...

The current Covid-19 (SARS-CoV-2) pandemic is causing a tremendous impact on all people in the world. use of masks part preventive measures spreading certain respiratory viral diseases, including Covid-19. One way to prevent viruses fabric masks, but there still shortage that nano filters are needed as material mask layer. purpose this research examine effect nanosilver concentration and nano-T...

in this study, microball nanosilver was produced with dimensions of about 1 micrometer in order to reduce the risks of absorption of nanosilver particles through skin and inhalation. different concentration levels of silver have been used in making of hand-sheets. the antibacterial properties of all hand-sheets were evaluated again escherichia coli and bacillus subtilis bacteria. results indica...

Background: The current type of nanoparticle that attracts a lot attention in the pharmaceutical field is Nanosilver because it can act as an antimicrobial. Objective: aim this study was to obtain gel preparation from katuk leaf extract, which effective antibacterial agent against acne. Methods: Katuk extract remains reducing synthesis using green method. characterization performed PSA, FTIR an...

This research has the purpose to determine characteristics of synthesis 20 ppm nanogold using TEM, effect adding on antioxidant activity Moringa leaves, and best concentration that supports increasing in leaves. Nanogold nanosilver were synthesized bottom-up methods. The concentrations used for leaf extract 5, 10, 15, 20, 25, 30 ppm. is Nanosilver at a had inhibition antibacterial activity. Tes...

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). ...
