The aim of this study was to evaluate the effects silver nitrate (AgNO3) and nano-silver (Ag-NPs) on physiological biochemical characteristics, quality grape bunches during a cold storage period. For investigations, two varieties grapes were used, Shine Muscat Kyoho, with different concentrations AgNO3 Ag-NPs post-harvest dipping. data indicated that enhanced fruits’ longevity quality. Dependin...

Different functions were imparted to ramie fibers through treatment with noble metal nanoparticles including silver and gold nanoparticles. The in situ synthesis of silver and gold nanoparticles was achieved by heating in the presence of ramie fibers in the corresponding solutions of precursors. The unique optical property of synthesized noble metal nanoparticles, i.e., localized surface plasmo...

Surface-enhanced Raman scattering (SERS) substrates with high density and uniformity of nanogaps are proven to enhance the reproducibility and sensitivity of the Raman signal. Up to now, the syntheses of a highly ordered gold or silver superstructure with a controllable nanoparticle size and a well-defined particle gap have been quite limited. Here, we reported an ordered mesoporous silver supe...

In this study, the modification of macroporous α-Al2O3 ceramics with AlOOH nanostructures impregnated silver particles is carried out using bicomponent Al/Ag nanoparticles obtained by simultaneous electrical explosion Al and Ag wires. Nanoparticle suspension impregnation porous followed oxidation water shown to lead formation a continuous nanosheet coating on ceramic surface, releasing surface ...

Skin wound healing is time-consuming and frequently accompanied by bacterial infections the development of scars. The rise antibiotic-resistant strains has sparked a growing interest in naturally occurring bioactive substances, like curcumin, that possess wound-healing capabilities. Silver natural antimicrobial agent, finds extensive use specialized dressings. nanoparticles (AgNPs) were synthes...

BACKGROUND This study was carried out to evaluate the biocompatibility of zeolite-silver-zinc (Ze-Ag-Zn) nanoparticles and their effect on the compressive strength of Mineral Trioxide Aggregate (MTA). MATERIAL AND METHODS Biocompatibility was evaluated by an MTT assay on the pulmonary adenocarcinoma cells with 0.05, 0.1, 0.25, 0.5, 1 and 5 mg/mL concentrations of Ze-Ag-Zn. For compressive str...

The photocatalytic activity of titanium dioxide (TiO2) was improved by forming a matrix containing silver (Ag) nanoparticles (NPs) prepared plasma process. plasma-assisted reduction process successfully formed metallic Ag on the surface TiO2 NP to create Ag-TiO2 Janus heterostructure. synthesized NPs were characterized using Brunauer, Emmett, and Teller analysis, transmission electron microscop...

Silver nanoparticles (AgNPs) can enter eukaryotic cells and exert toxic effects, most probably as a consequence of the release of Ag+ ions. Due to the elusive nature of Ag+ ionic species, quantitative information concerning AgNP intracellular dissolution is missing. By using a synchrotron nanoprobe, silver is visualized and quantified in hepatocytes (HepG2) exposed to AgNPs; the synergistic use...

We employed a simple and effective electroless (EL) plating approach to produce silver nanoparticles (NPs) on bare silicon, on dielectric ZnO nanowires (NWs) and on Si NWs, respectively. The surface stability of the homogeneous Ag NPs formed on the ZnO NW surfaces was investigated by surface enhanced Raman spectroscopy (SERS), which show that the attachment of thiol to the Ag surface can slow d...

The adsorption of l-histidine on gold (Au) and silver (Ag) nanoparticle surfaces has been comparatively analyzed by means of surface-enhanced Raman scattering (SERS). The SERS spectra of l-histidine on Ag were found to be quite different from those on Au, indicating dissimilar adsorption structures depending on metal substrates. Most peaks of l-histidine on Ag appeared to be due to coordination...
