In this study, Strychnos phaeotricha liana bark extract was used as a metabolite container both on the surface of metallic nanosilver and encapsulated by chitosan polymer. The plant able to reduce Ag+ into Ag0 efficiently, encapsulation rate determined. synthesized nanoderivatives were characterized using ultraviolet-visible spectrophotometry (UV-Vis), Fourier transform infrared (FTIR) spectros...

background: nanosilver particles are among the potentially candidates for modulating the redox status and changing the growth, performance and quality of plants because of their physicochemical characteristics.   objective: this study was carried out to elucidate the potential effects of nanosilver particles application on variations of photosynthetic pigments (chlorophyll and carotenoids) and ...

Silver nanoparticles are gaining importance as an antimicrobial agent in wound dressings. Chitin is a biopolymer envisioned to promote rapid dermal regeneration and accelerate wound healing. This study was focused on the evaluation of chitin membranes containing silver nanoparticles for use as an antimicrobial wound dressing. Silver nanoparticles were synthesised by gamma irradiation at doses o...

Background: Chicken sertoli cells are a model to evaluate the effects of toxic Materialss. These cells can actively proliferate in the in vitro conditions and they are able to passage several times. Because of the widespread use of nanosilver in life and also few studies on the effects of these Materialss on different cell lines, evaluation of its toxic effects is felt. Mechanism of nanosilver ...

antibiotic resistance to microorganisms is one of the major problems faced in the field of wound care in burns patients. silver nanoparticles have come up as potent antimicrobial agent and are being evaluated in diverse medical applications ranging from silver based dressings to silver coated medical devices. we aimed in present study to test the release of nanosilver from nanosilver wound dres...

the purpose of this study was to examine the effectiveness of nanosilver colloid as a new antimicrobial agent against erwinia in tissue culture of sugar beet for the recovery of the contaminated doubled haploid plantlets. the nanosilver colloidal solution of 4000 ppm was diluted in different concentrations (0, 50, 75, 100 and 125 ppm) and was added to the solid ms medium. in a factorial experim...

The European Commission should be regulating nanosilver, not asking for yet another report on its impact on health and the environment.

b ackgro un d : the antimicrobial activity of silver nanoparticles has been investigated in medical fields in recent years, but there are few studies regarding its effect on oral microorganisms. the aim of the present study was to evaluate the in vitro antimicrobial and toxicity properties of nanosilver against two dental plaque microorganisms  and human gingival fibroblast (hgf) cell line. me ...
