The nanocaps array of TiO₂/Ag bilayer with different Ag thicknesses and co-sputtering TiO₂-Ag monolayer with different TiO₂ contents were fabricated on a two-dimensional colloidal array substrate for the investigation of Surface enhanced Raman scattering (SERS) properties. For the TiO₂/Ag bilayer, when the Ag thickness increased, SERS intensity decreased. Meanwhile, a significant enhancement wa...

Following exposure to a diet containing control (no added Ag), AgNO3, Ag NPs or Ag2S NPs, Ag-containing particles were found in organs of all treatments, with the highest concentrations following AgNO3 NP.

silver nanoparticles (ag nps) have been widely used as new potent antimicrobial agents in cosmetic and hygienic products. present study compares the tissue levels of ag nps in different organs of guiana pigs quantitatively after dermal application and analysis the morphological changes and pathological abnormalities on the basis of the ag nps tissue levels. before toxicological assessments,the ...

objective(s):   metal nanoparticles (nps) offer a wide variety of potential applications in pharmaceutical sciences due to the unique advances in nanotechnology research. in this work, bimetal ag-au alloy nps were prepared and their combinations with other antibiotics were tested against staphylococcus aureus.   materials and methods: firstly, ag-au alloy nps with au/ag molar ratio of 1:1 was f...

The mechanism(s) responsible for autoimmunity to DNA and nucleosomes in SLE is largely unknown. We have demonstrated that nucleosome-polyomavirus T-Ag complexes, formed in context of productive polyomavirus infection, activate dsDNA-specific B cells and nucleosome-specific CD4(+) T cells. To investigate whether de novo expressed T-Ag is able to terminate nucleosome-specific T cell tolerance and...

Green chemistry - also called sustainable chemistry - as the cost-effective and environmentally friendly techniques have been gaining more attention recent years. Here, we introduced a fast, non-toxic and sustainable method to synthesize Ag nanoparticles. Various parameters are involved in the bio-synthesis of Ag nanoparticles/multi-walled carbon nanotubes (Ag/MWf-CNT) composites, including...

For the first time the extract of the plant of Tilia platyphyllos was used to green synthesis of Ag nanoparticles (NPs) supported on Ziziphus jujuba kernel as an environmentally benign support. Ag NPs/ Ziziphus  jujuba  kernelas  an  effective  catalyst  was  prepared  through reduction  of Ag+ions using Tilia  platyphyllos extractas  the  reducing  and capping agent  and Ag  NPs immobilization...

[Ag(2)(NH(3))(2)(salH)(2)] (salH(2)=salicylic acid) was synthesised from salicylic acid and Ag(2)O in concentrated aqueous NH(3) and the dimeric Ag(I) complex was characterised using X-ray crystallography. The complex is centrosymmetric with each metal coordinated to a salicylate carboxylate oxygen and to an ammonia nitrogen atom in an almost linear fashion. The two [Ag(NH(3))(salH)] units in t...
