In this article, a series of mixed-ligand Ag(i) coordination polymers, namely, Ag(L1)H(2)O (), Ag(2)(hmt)(2)(L1)(2) (), [Ag(HL2)]H(2)O (), [Ag(L2)(biim)][Ag(biim)] (), [K(5)(L3)(2)][Ag(H(2)O)(2)] (), [Ag(2)(L3)(3-iso)][Ag(3-iso)]5H(2)O (), [Ag(3)(L3)(bipy)(3)(H(2)O)]6H(2)O (), [Ag(3)(L3)(biim)(3)]H(2)O (), and [Ag(3)(L3)(hmt)(2)(H(2)O)(3)]H(2)O () (where hmt = hexamethylenetetramine, bipy = 4,4...

In the present study, the extract of the plant of Oenothera biennis was used to green synthesis of silver nanoparticles (Ag NPs) as an environmentally friendly, simple and low cost method. And Additionally, TiO2/SiO2 was prepared via facile sol-gel method using starch as an important, naturally abundant organic polymer as an ideal support. The Ag NPs/TiO2/SiO<su...

The asymmetric unit of the title coordination complex, [Ag2Br2(C5H8N2)2] n , comprises a monodentate 1-ethyl-imida-zole ligand, an Ag(+) cation and a μ3-bridging Br(-) anion, giving a distorted tetra-hedral AgNBr3 stereochemistry about the Ag(+) cation [Ag-N = 2.247 (2) Å and Ag-Br = 2.7372 (4)-2.7523 (4) Å]. Two bridging bromide anions generate the dimeric [Ag2Br2(C5H8N)2] repeat unit [Ag⋯Ag =...

In this research, silver nanoparticles (Ag NPs) were prepared by a low-cost, rapid, simple and ecofriendly approach using Grape fruit extract as a novel natural reducing and stabilizing agent. The product was characterized by UV-visible spectroscopy, X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), field emission scanning electron microscopy (FESEM), energy-dispersive X-...

A facile boiling water synthesis protocol has been developed to synthesize thiolated Ag nanoclusters with a core-shell Ag(0)@Ag(i)-thiolate structure, which was formed through condensation of Ag(i)-thiolate complexes on the surface of an in situ formed Ag(0) core. The as-synthesized thiolated Ag nanoclusters feature strong luminescence via aggregation-induced-emission (AIE).

the synthesis, characterization and application of biologically synthesized nanomaterials are an important aspect in nanotechnology. the present study deals with the synthesis of silver nanoparticles (ag-nps) using the aqueous extract of red seaweed gelidiella acerosa as the reducing agent to study the antifungal activity. the formation of ag-nps was confirmed by uv-visible spectroscopy, x-ray ...

Pseudomonas aeruginosa is one of the most common causes of keratitis. The current study was done to evaluate the therapeutic effects of antibacterial combinations with Silver nanoparticles (Ag-NPs) and Ciprofloxacin in experimental Pseudomonas keratitis. Sixty four New Zealand rabbits were prepared. All rabbits were randomly categorized into eight groups (each group containing eight rabbits): C...

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 reactions of human and bovine retinal S-antigen (S-ag) with polyclonal rabbit antibodies were compared in ELISA, immunoblotting and inhibition ELISA. Titrations in ELISA with plastic-adsorbed S-ags revealed that the great majority (70-100%) of human S-ag epitopes and anti-human S-ag antibodies were cross-reactive. In contrast, the cross-reactivity of bovine S-ag (25%) and anti-bovine S-ag a...
