Innovative CMC-based hydrogels with great potentials for usage in medical area were principally synthesized as per two strategies .The first involved reaction of epichlorohydrin in alkaline medium containing silver nitrate to yield silver nano-particles (AgNPs)-loaded CMC hydrogel. While CMC acted as stabilizing for AgNPs, trisodium citrate was added to the reaction medium to assist CMC in esta...

Listeria monocytogenes is a serious foodborne pathogen that can contaminate food during processing and can grow during food shelf-life. New types of safe and effective food contact materials embedding antimicrobial agents, like silver, can play an important role in the food industry. The present work aimed at evaluating the in vitro growth kinetics of different strains of L. monocytogenes in th...

Current technology, Inkjet is an accepted technology for dispensing small volumes of material (50 – 500 picolitres). Currently traditional metal-filled conductive adhesives cannot be processed by inkjetting (owing to their relatively high viscosity and the size of filler material particles). Smallest droplet size achievable by traditional dispensing techniques is in the range of 150 μm, yieldin...

Complexation of metallic silver nano particles (NPs) with Pyrromethene laser dyes (PM567, PM597) has significant effect on lifetime, photostability and the fluorescence efficiency. These enhancement of optical properties of the complex in solution due to surface Plasmon resonance (SPR) have been promised higher efficiencies in case of [40% Ag NPs: PM dye] complexes for dye laser systems. The fl...

background and aims. incorporation of nano-particles to orthodontic bonding systems has been considered to prevent enamel demineralization around appliances. this study investigated cytotoxicity of transbond xt adhesive containing 1 wt% titanium dioxide (tio2) nano-particles. materials and methods. ten composite disks were prepared from each of the conventional and tio2-containg composites and ...

magnetic nanoparticles attracted a great deal of attention in the medical applications due to their unique properties. the most exceptional property of magnetic particles is their response to a magnetic force, and this property has been utilized in applications such as drug targeting, bioseparation, contrast agents in magnetic resonance imaging (mri) and heating mediators for cancer therapy. in...

background: this study was performed to determine antifungal activity of silver nanoparticles (nano-ag) compared to voriconazole on clinical and standard strains of aspergillus fumigatus. materials and methods: inhibitory potency of nano-ag was determined using microtiter broth dilution method. susceptibility tests were performed against a. fumigatus isolated from bal (bronchoalveolar lavage) o...

A colour ink jet printing with improved water fastness property was produced by using of special component in the ink’s formulation. In this study, the water fastness of ink jet prints which used acrylic/nano-silver resin nano-composite ink instead of conventional resin in ink’s formulation was examined. The nano composite resin was prepared via miniemulsion polymerization of acrylate monomers ...

The effect of poly(N-vinylpyrrolidone) (PVP) concentration on the synthesis and properties of silver nanoparticles (AgNPs) was investigated. Nanoparticles have been prepared by a chemical reduction method from the aqueous solution of silver nitrate and PVP as a stabilizing agent in the presence of sodium borohydride as a reducing agent. The nanosized silver colloids have been characterized usin...
