Investigators from Hungarian Academy of Sciences Have Reported New Data on Photocatalytics (LED-light Activated Antibacterial Surfaces Using Silver-modified TiO2 Embedded in Polymer Matrix)

By a News Reporter-Staff News Editor at Life Science Weekly -- Current study results on Photocatalytics have been published. According to news reporting originating from Szeged, Hungary, by NewsRx correspondents, research stated, "Silver functionalized TiO2/poly(etyl-acrylate co methyl-methacrylate) nanohybrid films were proved to inactivate nosocomial bacteria. The films were prepared on glass plates by spray coating technique and their thickness were 1.48 +/- 0.1 mu m. During photocatalysis, the films were illuminated with visible LED-light source (lambda = 405 nm)."

Our news editors obtained a quote from the research from the Hungarian Academy of Sciences, "The optical and photooxidation properties of prepared nanocomposite films were characterized by diffuse reflectance measurements and the photocatalytic properties were tested in ethanol photooxidation monitored by gas-chromatography experiments. The photocatalytic activity of the nanohybrid films were tested under visible light illumination against bacteria causing nosocomial infections, such as methicillin resistant Staphylococcus aureus, Enterococcus faecium, Pseudomonas aeruginosa and Acinetobacter baumannii. The investigation of the antibacterial activity of the silver functionalized TiO2 was carried out by measuring the survival ratio of the original amount of the bacteria on the nutrient agar plate. To verify the photooxidation effect of the reactive films, parallel experiments were carried out without any light source."

According to the news editors, the research concluded: "All of the investigated bacteria were inactivated on the surface of the nanohybrid films within 120 minutes of LED-light illumination."
