The photocatalytic activity of nanocomposites based on theta-modification aluminum oxide Al2O3 with different TiO2 content for heterogeneous photocatalysis and biodegradation pathogenic microorganisms under the action LED radiation a wavelength 405 nm has been studied. It was found that all investigated have activity. maximum antibacterial efficiency composites 8 wt% (reduction CFU Staphylococc...

Bacterial infection associated with indwelling medical devices and implants is a major clinical issue, and the prevention or treatment of such infections is challenging. Antimicrobial coatings offer a significant step toward addressing this important clinical problem. Antimicrobial coatings based on tethered antimicrobial peptides (AMPs) on hydrophilic polymer brushes have been shown to be one ...

Silver nanoparticle-based antimicrobials can promote a long lasting bactericidal effect without detrimental toxic side effects. However, there is not a clear and complete protocol to define and relate the properties of the particles (size, shape, surface charge, ionic content) with their specific activity. In this paper, we propose an effective multi-step approach for the identification of a 'p...

BACKGROUND The efficacy of antimicrobial urinary catheters in hospitalized patients is poorly defined. PURPOSE To assess currently marketed antimicrobial urinary catheters for preventing catheter-associated urinary tract infection (UTI). DATA SOURCES Electronic databases, conference proceedings, bibliographies, trialists, and catheter manufacturers (search dates, 1966 to June 2005). STUDY...

Development of materials with an antimicrobial activity is fundamental for different sectors, including medicine and health care, water and air treatment, and food packaging. Electrospinning is a versatile and economic technique that allows the incorporation of different natural, industrial, and clinical agents into a wide variety of polymers and blends in the form of micro/nanofibers. Furtherm...

Animal origin foods are widely distributed and consumed around the world due to their high nutrients availability but may also provide a suitable environment for growth of pathogenic and spoilage microorganisms. Nowadays consumers demand high quality food with an extended shelf life without chemical additives. Edible films and coatings (EFC) added with natural antimicrobials are a promising pre...

Antiviral Coatings During the COVID-19 pandemic, robust and effective antimicrobial antiviral fabrics have been required. In article 2104298, Michael D. Dickey, Vi Khanh Truong, Tae-il Kim, co-workers propose an easy-to-control straightforward method to coat gallium liquid metal (LM) particles on a wide range of facilitate deposition copper alloy (LMCu) particles. This coating can offer adhesio...

OBJECTIVES Implantable devices are major risk factors for hospital-acquired infection. Biomaterials coated with silver oxide or silver alloy have all been used in attempts to reduce infection, in most cases with controversial or disappointing clinical results. We have developed a completely new approach using supercritical carbon dioxide to impregnate silicone with nanoparticulate silver metal....

starch is found in abundance in nature and it is one of the raw materials used for food packaging because of the low price, biodegradability, good mechanical and barrier properties. the recycling ability of coating materials was significantly increased by using edible films and coating in comparison to traditional packaging and it could be an alternative for synthetic films. in this research, t...
