BACKGROUND: A new polyurethane foam dressing impregnated with 3% povidone-iodine (Betafoam; Genewell, Seoul, Korea) was recently developed based on the hypothesis that its physical properties, including improved moisture-retention capacity and antimicrobial activity, are at least as good as those achieved with the current foam dressings that contain silver, but also associated with reduced cost and cytotoxicity to host cells. The purpose of this in vitro study was to evaluate the efficacy of Betafoam by comparing its physical properties, antimicrobial activity, and cytotoxicity with those of 3 silver foam dressings (Allevyn-Ag [Smith & Nephew, Hull, United Kingdom]; Mepilex-Ag [Mölnlycke Health Care, Gothenburg, Sweden]; and PolyMem-Ag [Ferris MFG Corp, Burr Ridge, Illinois]) used worldwide...

Silver has been widely used as an effective antibacterial agent especially for treating burns and wounds. However, release of silver from materials often arouse side effects due to toxicity of silver towards mammalian cells. Argyria and argyrosis are well known problems of acute toxicity of silver towards human body. Immobilization of silver is an effective approach to reduce silver release. Herein, we present poly(vinyl alcohol) (PVA) composite nanofibers embedded with silver-anchored silica nanoparticles (SSNs) as a novel antibacterial material...

The biological way of metallic nanoparticles production using ecofriendly biocontrol agents are largely used to control many plant pathogenic microorganisms in agriculture. Hence, an attempt was made to evaluate the potential of suppressive activity of nanoparticles produced by an indigenous isolate, Trichoderma atroviride against a tea pathogenic fungus namely Phomopsis theae. The presence of biosynthesised nanoparticles was primarily confirmed through ultraviolet-visible spectroscopy analysis and was characterised using X-ray diffraction and scanning electron microscopy-energy dispersive X-ray analysis to delineate the size, shape and nature of particles...

The increasing prevalence of wound infections caused by antibiotic resistant bacteria is an urgent challenge facing modern medicine. To address this issue the expedient use of antimicrobial metals such as zinc, copper and silver were incorporated into an FDA-approved polymer (polycaprolactone - PCL) to produce filaments for 3D printing. These metals have broad-spectrum antimicrobial properties, and moreover, copper and zinc can enhance the wound healing process. 3D scanning was used to construct 3D models of a nose and ear to provide the opportunity to customize shape and size of a wound dressing to an individual patient...

Radionecrosis is a late, and difficult to treat,complication of radiotherapy performed on head and neck tumours, and it is difficult to treat. This process causes significant damage, not only in the skin, but also in muscular, nervous, vascular, and bone structures. This, in turn, leads to airway and digestive tract involvement, as well as a functional loss and a cosmetic defect that usually requires reconstructive surgery. Therefore, this process is associated with a significant loss in the quality of life of patients and involves a long hospital stay for treatment, as well as the necessary support measures...

A topical antimicrobial, silver oxynitrate (Ag7NO11), has recently become available that exploits the antimicrobial activity of ionic silver but has enhanced activity because highly oxidised silver atoms are stabilised with oxygen in a unique chemical formulation. The objective of this study was to use a multifaceted approach to characterise the spectrum of antimicrobial and antibiofilm activity of a wound dressing coated with Ag7NO11 at a concentration of 0.4 mg Ag/cm(2). Physiochemical properties that influence efficacy were also evaluated, and Ag7NO11 was found to release a high level of Ag ions, including Ag(2+) and Ag(3+), without influencing the pH of the medium...
