PVP-capped silver nanoparticles with a diameter of the metallic core of 70 nm, a hydrodynamic diameter of 120 nm and a zeta potential of -20 mV were prepared and investigated with regard to their biological activity. This review summarizes the physicochemical properties (dissolution, protein adsorption, dispersability) of these nanoparticles and the cellular consequences of the exposure of a br...
Phytostabilized silver nanoparticles are being widely studied for its various pharmacological properties. In the present study silver nanoparticles synthesized using Black pepper extract was evaluated for its acute toxicity and also for its anti inflammatory activity in carrageenan induced paw edema in rats. The anti inflammatory effect was also compared against the commercial silver nanopartic...
Recent theoretical progress in understanding the effect of silver nanoparticles on photo-induced orientation of liquid crystalline polymer was reviewed. The observed enhancement of photo-induced rate results from the surface plasmon resonance (SPR) of silver nanoparticles. And the observed reducing phenomena are attributed to the interaction between materials and silver nanoparticles. And then ...
Antibiotic resistant pathogens pose an enormous threat to the treatment of various serious infections. To overcome this condition, a periodic replacement of the new and existing antibiotic is necessary. Antibiotics in combination with biosynthesized silver nanoparticles minimize the antibiotic doses to cure the dreaded diseases. In this study, Silver nanoparticles were bio-synthesized by extrac...
Materials used in ossicular replacement prostheses must possess appropriate biological properties, such as biocompatibility, stability, no cytotoxicity. Due to the risk of infection (otitis media and chronic otitis media), it is desirable to use an antibacterial agent for illness prevention during the ossicular reconstruction. The goal of this work was to observe biological properties of a new ...
Silver nanoparticles are widely used in various sciences and industries. Widespread use of silver nanoparticles has caused entrance of it to the aquatic environment through Wastewater, so it is necessary to investigate the effects of silver nanoparticles on various aquatic organisms. The present study investigated the lethal concentration and bioaccumulation of silver nanoparticles and its comp...

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 ...
We present here comparative assessments of murine lung toxicity (biocompatibility) after in vitro and in vivo exposures to carbon (C-SiO2-etched), carbon-silica (C-SiO2), carbon-cobalt-silica (C-Co-SiO2), and carbon-cobalt oxide-silica (C-Co3O4-SiO2) nanoparticles. These nanoparticles have potential applications in clinical medicine and bioimaging, and thus their possible adverse events require...
nowadays, green chemistry and its advantages are generating interest of researchers toward ecofriendly biosynthesis of the metallic nanoparticles. in this research, a rapid, simple and green method was developed for the synthesis of silver nanoparticles using aqueous extract of prangos ferulaceae leaves. the synthesized silver nanoparticles were characterized by uv-vis spectroscopy, scanning el...
