Silver containing nanocomposites receive increasing attention as antibacterial coatings. In this study we report on production of such materials using combination of gas aggregation sources of Ag nanoparticles and plasma enhanced chemical vapour deposition performed in HMDSO/O2 working gas mixtures. The main attention is devoted to the investigation of solubility of Ag nanoparticles in water in...
Periprosthetic infection remains a challenging clinical complication. We investigated the antibacterial properties of pure (99.9%) magnesium (Mg) in vitro and in an in vivo rat model of implant-related infection. Mg was highly effective against methicillin-resistant Staphylococcus aureus-induced osteomyelitis and improved new peri-implant bone formation. Bacterial icaA and agr RNAIII transcript...
Introduction: Due to the increased antibiotic resistance of bacteria due to the uncontrolled use of antibiotics and the self-permeability of antibiotics, finding effective drugs with less complications is very important. Since traditional plants have good antibacterial properties, we decided to investigate the effect of methanolic extract of some samples from herbal plants of North Khorasan Pro...
background & objectives: nanotechnology is one of great important part of technology. nanoparticles can be used in different applications for industrial, medical, military and personal use. the objectives of this study were preparation of polystyrene/zno nanocomposite films via a simple method and investigation of antibacterial activity of them. methods: polystyrene /zno nanoparticle (ps/n...
background and objectives: due to the importance of finding of new antibacterial agents, the antibacterial properties of prosopis cineraria aerial parts were investigated using a bioassay guided fractionation scheme. materials and methods: the organic extract was prepared via maceration in methanol, followed by the fractionation using n-hexane and ethyl acetate. the mics of fractions were deter...
Polyethylene (PE) is one of the most common materials used for medical implants. However, it usually possesses low biocompatibility and insufficient antibacterial properties. In the work described here, plasma immersion ion implantation (PIII) is employed to implant silver into PE to enhance both its antibacterial properties and its biocompatibility. Our results show that Ag PIII can give rise ...
white spot lesions are observed in nearly 50% of patients undergoing orthodontic treatment. long-lasting antibacterial properties of orthodontic cements can reduce this phenomenon. the aim of this research was to compare antimicrobial activity of three commercial glass ionomer cements with three commercial zinc phosphate cements, over time, against streptococcus mutans and candida albicans. dir...
Lactoferrin (Lf), a member of the transferrin family of iron-binding proteins, is now known to have a number of properties, including antibacterial activity towards a broad spectrum of Gram-negative and Gram-positive bacteria. The mechanism of the antibacterial activity of Lf is complex and involves beside iron-chelation, direct action on bacteria and/or the activation of the immune system. Lac...
Biomaterials with antibacterial activity are widely developed for the treatment of bone infection. In the present study, hydroxyapatite (HAp) nanorods were prepared by green synthesis using Azadirachta indica and Coccinia grandis leaf extract. The prepared samples were characterized by various characterization techniques and the results indicate that the prepared samples are constituted of phas...
