Objective To compare the clinical efficacy and safety of oil gauze silver dressing and silver ions dressing on diabetic ulcers in elderly outpatients. Methods Twenty-two patients with Type-2 diabetic foot ulcers were included in the study conducted at Yantai Yuhuangding Hospital between April 2013 and April 2014. At the time of enrolment they were divided into the silver ions and oil gauze si...

A number of antimicrobial silver dressings based on different substrates and silver technologies have been introduced recently. Initial in vitro testing of a new cost-effective silver dressing* showed a strong dependence between silver release and the ionic strength and organic content of the extraction solution. To answer the question if all silver dressings show similar dependence on extracti...

There have been concerns raised over the treatment of acute burns with silver particles because of the potential toxicity caused by silver. As the wound heals, a membrane is formed between the silver particle and the blood, but this membrane is not impenetrable, which might lead to further silver absorption. This paper reports the in vitro cytotoxicity of silver-chitosan composites prepared as ...

Silver is a naturally occurring element. Similar to other metals, the ionized form of silver (Ag(+1)) has known antimicrobial properties. A number of wound dressings incorporating silver ion or silver compounds have recently been developed and marketed. In addition, the antimicrobial effects of silver are currently being promoted in consumer products such as clothing and household appliances. T...

according to circumstance of kerman sarcheshmeh cooper complex that its anode slime is mainly consisted of cu, ag, au, pb and se. in this work, recovery of silver from anode slime and subsequent synthesis of silver nanoparticles from leaching solution was made. silver was separated from anode slime by using of hno3 and hcl. x-ray fluorescence spectroscopy (xrf) was used to characterize anode sl...

In the present study, synthesis, characterization, and the antibacterial activity of silver nanoparticles from native isolate of Corynebacterium glutamicum has been reported. Silver nanoparticles were synthesized by challenging the dried biomass of C. glutamicum with aqueous diamine silver ([Ag (NH3)2]+) containing 1 mM AgNO3. Synthesized silver nanoparticles (AgNPs) were characterized by ultra...

The in vitro study of antibacterial activity of silver nanoparticles (NPs), prepared via modified Tollens process, revealed high antibacterial activity even at very low concentrations around several units of mg/L. These concentrations are comparable with concentrations of ionic silver revealing same antibacterial effect. However, such low concentrations of silver NPs did not show acute cytotoxi...

The accumulation of Ag by the marine herbivorous gastropod, Littorina littorea, has been studied in a series of exposures in which the metal was added in aqueous form and as nanoparticles, both in the presence and absence of contaminated algal food (Ulva lactuca). Significant accumulation occurred in the gill, kidney, stomach and visceral mass when the snail was exposed to aqueous Ag in the abs...

Nanotechnology is a cutting-edge field of science with the potential to revolutionize today's technological advances including industrial applications. It is being utilized for the welfare of mankind; but at the same time, the unprecedented use and uncontrolled release of nanomaterials into the environment poses enormous threat to living organisms. Silver nanoparticles (AgNPs) are used in sever...

In this work, the thermal and electrical transport in an individual silver nanowire is characterized down to 35 K for in-depth understanding of the strong structural defect induced electron scattering. The results indicate that, at room temperature, the electrical resistivity increases by around 4 folds from that of bulk silver. The Debye temperature (151 K) of the silver nanowire is found 36% ...
