Bacterial infections, especially by antimicrobial resistant (AMR) bacteria, are an increasing problem worldwide. AMR is especially a problem with health care-associated infections due to bacteria in hospital environments being easily transferred from patient to patient and from patient to environment, and thus, solutions to prevent bacterial transmission are needed. Hand washing is an effective...

the silver nanoparticles are well-known for their antimicrobial, anti-inflammatory wound healing abilities. we synthesized silver nanoparticles using chemical reduction method and the formation of the silver nanoparticles was characterized by uv-vis absorption spectroscopy, ft-ir and sem techniques. the minimum inhibitory concentration of the synthesized nanoparticles was determined for both gr...

This paper reports the effect of soda-lime-glass-nAg coating on the viability of an in vitro biofilm of Streptococcus oralis. Three strains (ATCC 35037 and two clinical isolates from periodontitis patients) were grown on coated with glass, glass containing silver nanoparticles, and uncoated titanium alloy disks. Two different methods were used to quantify biofilm formation abilities: crystal vi...

The Silver SPR chip was modified by alkaline-silane condensation with aminopropyltriethoxysilane (APTES) in NaOH aqueous solution at different times. Silver sputtered slides coated with APTES were immersed in NaOH solution, enabling us to produce silver surfaces homogeneously covered with APTES. The surface properties of grafted APTES on sputtered silver surface as a occasion of time were studi...

In this research, we investigated the influence of the surface coatings of silver nanowires on the sensitivity of surface acoustic wave (SAW) humidity sensors. Silver nanowires, with poly(vinylpyrrolidone) (PVP), which is a hydrophilic capping agent, were chemically synthesized, with an average length of 15 µm and an average diameter of 60 nm. Humidity sensors, with 433 MHz frequency dual-port ...

CONTEXT Ventilator-associated pneumonia (VAP) causes substantial morbidity. A silver-coated endotracheal tube has been designed to reduce VAP incidence by preventing bacterial colonization and biofilm formation. OBJECTIVE To determine whether a silver-coated endotracheal tube would reduce the incidence of microbiologically confirmed VAP. DESIGN, SETTING, AND PARTICIPANTS Prospective, random...

Acoustic vibrations of single gold nanorods coated with silver were investigated. We used single-particle pump-probe spectroscopy to monitor the silver deposition through the particle vibrations. Two vibration modes, the breathing mode and extensional mode, are observed, and the vibrational frequencies are measured as functions of the amount of silver deposited on single gold nanorods. The brea...

plants or natural resources have been found to be a good alternative method for nanoparticles synthesis. in this study, polyaniline coated silver nanoparticles (agnps) synthesized from piper betle leaves extract were investigated for their antibacterial activity. silver nanoparticles were prepared from the reduction of silver nitrate and nabh4 was used as reducing agent. silver nanoparticles an...

The aim of the study was to analyze how per os application of hydrocolloids of silver nanoparticles (22 nm) and lipid-coated silver nanoparticles (5 nm) affect the immune, redox, and lipid status of the blood of broiler chickens. The experiment was conducted on 60 chickens. The first group was the control (Group C). The chickens in Group II received a silver nanoparticle hydrocolloid (Ag-nano) ...
