COVID-19 virus has spread almost all over the world, including Indonesia until now. in people with diabetes mellitus have a risk of exacerbating symptoms. Diabetes is disease caused by high blood sugar levels. Nanogold very strong anti-oxidant capability, while nanosilver anti-bacterial properties. In this research, nanogold-nanosilver was presented form health drinking water packaged 1 L bottl...

This article presents a proposed insight into the anti-viral potential of silver nanoparticles against novel coronavirus disease (COVID-19). Possible mechanisms influence on are considered. Models nanosilver complexes with spike protein amino acids were constructed using computer quantum-chemical modeling. The values electron density distribution, highest occupied molecular orbital, lowest unoc...

  Background: Nanosilver particles are among the potentially candidates for modulating the redox status and changing the growth, performance and quality of plants because of their physicochemical characteristics.   Objective: This study was carried out to elucidate the potential effects of nanosilver particles application on variations of photosynthetic pigments (chlorophyll and carotenoids) an...

The aim of this study was to use aqueous suspensions of silver nanoparticles with a wide spectrum of particle sizes, variable morphology, high stability, and appropriate physicochemical properties to examine their bactericidal and fungicidal properties against microorganisms present in poultry processing plants. At the same time, the particles were tested for preventing the production of odorog...

This paper describes a process of obtaining nanosilver and nanogold based on chemical reduction using substances contained in the aqueous extract of dog rose (Rosa canina). The resulting products were subjected to spectrophotometric analysis (UV-Vis), and testing of the nanoparticles' size and suspension stability was carried out by measuring the electrokinetic potential, ζ, via dynamic light s...

 Effect of nanosilver particles was studied on the hatchability of rainbow trout (Oncorhynchus mykiss) egg and survival of the produced larvae at about 12ºC. In the first experiment the water-based nanosilver particles was used at concentrations of 0.5, 1, 2 and 4 mgL-1 for 30 minutes per day starting 24 hour post egg incubation until the hatching time. The mean percentage of hatchability reach...

The current paper reports on the relase properties of conductive fabrics coated with proteinaceous microspheres containing a dye. The release of the dye was achieved by passing an electric current through the fabric. The conductivity of the polyester fibers resulted from nanosilver (Ag NPs) coated on the surface of these fibers. Both types of coatings (nanosilver coating and the coating of the ...

in vitro antifungal activity of silver nanoparticles, at concentrations of 6, 8, 10, 12, 14 and 16 ppm, was studied on five phytopathogenic fungi, and a biocontrol agent. then effect of silver nanoparticle at 6 ppm (optimum concentration) was evaluated on macrophomina phaseolina in greenhouse. for in vitro experiment, the fungal isolates were grown on potato dextrose agar medium amended with si...
