The in vitro activity of seven metallic compounds was tested against penicillinase (beta lactamase) producing strains of Neisseria gonorrhoeae (PPNG) and non-PPNG strains. On a weight basis, the mercurials showed the greatest in vitro activity. Phenylmercuric borate, thiomersal, and mercuric chloride inhibited 90% of all strains at concentrations of 5 mg/l, 5 mg/l, and 20 mg/l respectively. Sil...

Capping silver nanoparticles with LL37 peptide eradicates the antiproliferative effect of silver on primary skin cells, but retains the bactericidal properties of silver nanoparticles with activities comparable to silver nitrate or silver sulfadiazine. In addition, LL37 capped silver nanoparticles have anti-biofilm formation activity.

The first silver-FOX, silver-ammonia-FOX, and silver-amine-FOX compounds were synthesized by the reactions of silver nitrate with K-FOX or guanidine-FOX in water, aqueous ammonia, and amines, respectively. The crystal structure of silver-ammonia-FOX exhibits unique covalent bonding behavior, which is supported by NBO calculations.

Nanotechnology enables development and production of novel silver-based composite materials. We used in vitro tests to demonstrate the antimicrobial activity of a silver-silica nanocomposite compared to the activities of conventional materials, such as silver nitrate and silver zeolite. A silver-silica-containing polystyrene material was manufactured and shown to possess strong antimicrobial pr...

The aim of the study was to synthesize silver nanoparticles by using filamentous fungus Penicillium sp. The fungal culture was isolated from the soil samples collected from agriculture fields in Vellore district, Tamil Nadu, India. The purified fungal isolates were inoculated in minimal medium and incubated at room temperature for three days. For the synthesis of silver nanoparticles, 50 ml of ...

The presence of either copper(I) or copper(II) chloride in the polyol reduction of silver nitrate facilitates the production of silver nanowires. Silver nanowires have applications in many areas, including electronics and catalysis. These wires are produced quickly (in approximately one hour), with the synthesis being easily performed in disposable glass vials, using only pipettes to deliver re...

There is an increasing interest in using of silver coated (silver nitrate, silver alloy, silver oxide) catheters for hospital patients. Clinical trials with silver-coated urinary catheters have shown conflicting results. The most often performed catheterization is for a short period of time. The above observations have encouraged the authors to investigate the influence of silver nitrate (AgNO3...

In the present investigation the effect of cobalt chloride (CoCl ), ethylene biosynthesis inhibitor and 2 silver nitrate (AgNO ), ethylene perception inhibitor was studied on the seed germination of Vigna radiata. 3 While ethylene slightly promoted germination, both the inhibitors decreased the germination percentage. However, Ag was more effective in retarding germination than Co . A combined ...
