BACKGROUND In atopic eczema (AE), skin colonization with Staphylococcus aureus is known to play a major triggering and possibly pathophysiological role. METHODS In this open-labeled controlled side-to-side comparative trial, affected sites (flexures of both elbows) in 15 patients diagnosed as having generalized or localized AE were evaluated regarding S. aureus colonization and clinical sever...

In this work, an simple and fast method based solid phase extraction for preconcentration and separation of trace amount of Fe(III) ions from water samples prior to its determination by flame atomic absorption spectrometry (FAAS) was developed. The silver nanoparticles coated silica gel was modified by morin and then it was used as a adsorbent. The silver nanoparticle coated silica gel was prep...

The aim of this study was to evaluate gastrointestinal microbial population response and performance of broiler chickens fed organic acids and silver nanoparticles coated on zeolite under heat stress condition. In this experiment, 375 one-day old broiler chicks (Cobb 500) were randomly divided into 5 treatments containing 5 replicates with 15 birds in each replicate. Five dietary treatments wer...

ᅟ: Ag-coated spherical Li4Ti5O12 composite was successfully synthesized via a sol-gel-assisted hydrothermal method using an ethylene glycol and silver nitrate mixture as the precursor, and the influence of the Ag coating contents on the electrochemical properties of its was extensively investigated. X-ray diffraction (XRD) analysis indicated that the Ag coating does not change the spinel struct...

Implant-associated infections (IAIs) are a dreaded complication mainly caused by biofilm-forming staphylococci. Implant surfaces preventing microbial colonization would be desirable. We examined the preventive effect of a silver-coated titanium-aluminum-niobium (TiAlNb) alloy. The surface elicited a strong, inoculum-dependent activity againstStaphylococcus epidermidisandStaphylococcus aureusin ...

Silver nanowire-based flexible transparent electrodes have critical problem, in spite of their excellent electrical and optical properties, that the electrical conductance and transparency degrade within several days in air because of oxidation of silver. To prevent the degradation of the silver nanowire, we encapsulated Ag-NWs with thin TiO2 barrier. Bar-coated silver nanowires on flexible pol...

Background: Catheter-related infections (CRI), thrombosis, and stenosis are among the most frequent complications associated with catheters which are inserted in vessels as vascular access. These problems are usually related to the handling of the staff, the catheter materials, and the surface properties of the catheter. To mitigate such complications surface treatment process of the outer surf...

In the present study, silver nanoparticles (AgNPs) were synthesized via biological reduction of silver nitrate using extract of the fungus Fusarium verticillioides (green chemistry principle). The synthesized nanoparticles were spherical and homogenous in size. AgNPs were coated with polyethylene glycol (PEG) 6000, sodium dodecyl sulfate (SDS), and β-cyclodextrin (β-CD). The averaged diameters ...

We report that self-assembled monolayers of colloidal silver nanoparticles can increase the intensity of the surface plasmon-coupled emission (SPCE) signal from sulforhodamine 101 (S101). The S101 was spin coated on a glass slide coated with a layer of continuous silver, and a silica layer upon which the nanoparticle layer was self-assembled. Of the various colloid sizes studied, the 40 nm coll...
