The potential effectiveness of a silver nylon (SN) fabric as an antimicrobial agent was evaluated in a series of in vitro experiments. The results indicated that silver ions from the SN fabric penetrated 2 mm of agar and killed a challenge of 6.9 X 10(7) Pseudomonas aeruginosa, 4.1 X 10(7) Staphylococcus aureus, and 1.4 X 10(7) Candida albicans organisms per cm2 of SN fabric after 24 h of incub...

Colorful clusters: Silver nanoclusters consisting of only a few atoms exhibit large chemical-environment-responsive shifts of their optical absorption and emission bands, that is, large solvatochromism (see picture). The photophysical characteristics and electrochemiluminescence of the Ag clusters give them remarkable advantages over larger nanoparticles in applications such as molecular sensing.

BACKGROUND Wound healing is the process of repair following an injury to the skin and other soft tissues. In this study, the effect of n-hexane d-chloromethane extract (1: 1) of root Onosma bulbotrichum DC on the second degree burn in rabbit model was investigated. METHODS Thirty-six adult rabbits of both sexes were randomly divided into six groups, control (without treatment), negative cont...

Considerable research has been conducted and published regarding the efficacy of ARROWgard Blue, chlorhexidine and silver sulfadiazine in suppressing microbial colonization, and their effect on reducing hospital costs. A catheter-related bloodstream infection can prolong hospitalization and substantually add to the cost of hospitalization. In addition, numerous studies have investigated the inc...

Novel hairpin DNA probes are designed and constructed based on target-induced in situ generation of luminescent silver nanoclusters. This design allows specific and versatile detection of diverse targets with easy operation and low cost.

Very small ( approximately 2 nm) silver nanoparticles can be readily prepared using p-phosphonated calixarenes as templating agents and surfactants, at the same time allowing the use of hydrogen gas as an environmentally benign reductant.

Silver is the ideal material for plasmonics because of its low loss at optical frequencies but is often replaced by a more lossy metal, gold. This is because of silver's tendency to tarnish and roughen, forming Ag(2)S on its surface, dramatically diminishing optical properties and rendering it unreliable for applications. By passivating the surface of silver nanostructures with monolayer graphe...

Silver nanoprisms of different sizes influence fluorescence enhancement in YVO4:Eu(3+) nanoparticles to various degrees under excitation of green light (532 nm). The local field generated by silver nanoprisms and their dimers is simulated through the FDTD method and a direct correlation with fluorescence enhancement is established.
