Antimicrobial activity of novel nanostructured Cu-SiO2 coatings prepared by chemical vapour deposition against hospital related pathogens.

There is increasing recognition that the healthcare environment acts as an important reservoir for transmission of healthcare acquired infections (HCAI). One method of reducing environmental contamination would be use of antimicrobial materials. The antimicrobial activity of thin silica-copper films prepared by chemical vapour deposition was evaluated against standard strains of bacteria used for disinfectant testing and bacteria of current interest in HCAI.

Durability of silver nanoparticulate films within a silica matrix by flame assisted chemical vapour deposition for biocidal applications.

Healthcare acquired infection (HCAI) rates have come under increasing scrutiny in recent years and been a major priority for health professionals in the UK and elsewhere. Of particular concern is the rise of so called 'superbugs', or those resistant to conventional antibiotics, such as Escherichia coli, Clostridium difficile and methicillin resistant Staphylococcus aureus (MRSA). The reasons for this rise are many and complex, but one important factor is bacterial survival rates on wards and other hospital areas.

Photocatalytic disinfection using titanium dioxide: spectrum and mechanism of antimicrobial activity.

The photocatalytic properties of titanium dioxide are well known and have many applications including the removal of organic contaminants and production of self-cleaning glass. There is an increasing interest in the application of the photocatalytic properties of TiO(2) for disinfection of surfaces, air and water. Reviews of the applications of photocatalysis in disinfection (Gamage and Zhang 2010; Chong et al.
