Microbicidal potential of silver nanoparticles (Ag-NPs) can be drastically improved by improving their solubility or wettability in the aqueous medium. In the present study, we report the synthesis of both green and chemical synthesis of Ag-NPs, and evaluate the effect of the dispersion qualities of as-prepared Ag-NPs from both methods on their antimicrobial activities. The green synthesis of A...

Plants are rich source of natural products used for centuries to cure various the plant-derived medicines are based upon the premise that they contain natural substances that can promote health and alleviate illness. Silver NPs represent material, which can be used as a potential antibacterial agent in medical applications and different commercial products due to its biological activity. Recent...

During this study, we report the green synthesis of silver nanoparticles (Ag NPs) using Euphorbia helioscopia Linn leaf extract for the synthesis of propargylamines. Also, the structural and optical properties are studied. The synthesized nanoparticles are characterized by TEM, XRD, FT-IR and UV-visible techniques. UV-visible studies show an absorption band at 440 nm due to surface plasmon reso...

The present paper describes the preparation and characterization of Polyvinyl Alcohol-Polypyrrole-Silver Nanocomposite (PVA-PPy-Ag NC) films. The prepared films were conducting, freestanding, flexible, and robust. Silver nanoparticles (Ag NPs) were synthesized from an aqueous solution of silver nitrate using trisodium citrate as a reductant. The casting solution for the films was prepared by in...

In the present study, the extract of the plant of Oenothera biennis was used to green synthesis of silver nanoparticles (Ag NPs) as an environmentally friendly, simple and low cost method. And Additionally, TiO2/SiO2 was prepared via facile sol-gel method using starch as an important, naturally abundant organic polymer as an ideal support. The Ag NPs/TiO2/SiO<su...

the nanomaterials have important application in different field of science such as biology and pharmacology, which draws the attention of biologists towards this field of study more than before. as the worldwide mortality rate is high due to the pathogens and especially because of the bacteria associated aeromonas and the antibacterial effect of metal nanoparticles is well known for centuries, ...

The aim of this study was focused on the bactericide test of Silver nanoparticles with an average diameter of 6 nm, over Escherichia coli, Staphylococcus aureus and Candida albicans and the treatment of a dermatosis of unknown etiology with a poly(hydroxy urethane-acrylate) gel (PHU) with a concentration of approximately 10 ppm AgNPs and a ratio-NHCOO-:RGD (Arg-Gly-Asp) on the macromolecular ch...

A microfluidic device with integrated novel silver nanoparticle (Ag NPs) decorated nanowall structures was fabricated via in situ electrodeposition of Cu-core/C-sheath nanowalls, followed by a facile in-channel silver galvanic replacement reaction method at room temperature. The integrated microfluidic devices with Ag NPs decorated nanowalls, serving as a highly active Raman substrate, were the...

1 Nurse practitioners (NPs) have been caring for children since L.C. Ford and H.K. Silver pioneered the concept in the 1960s, and now, NPs also care for children in subspecialty, acute, and critical care (Silver, Ford, & Day, 1968). Reductions in resident duty hours in 2003 and 2011 (Schwartz et al., 2011) coupled with the primary care focus of the pediatric resident curriculum (Guralnick et al...

OBJECTIVES Silver nanoparticles (Ag-NPs) are used widely in bedding, water purification, tooth paste and toys. These nanoparticles can enter into the body and move into the hippocampus. The aim of this study was to investigate the neurotoxicity of silver nanoparticles in the adult rat hippocampus. MATERIALS AND METHODS 12 male Wistar rats were randomly divided into two experimental and contro...
