Název v původním jazyce

Antimicrobial and Photocatalytic Effect of Silicate and Silicone Hygienic Coatings

Popis výsledku v původním jazyce

Antimicrobial and photocatalytic effect of silicate and silicone paints were tested. Silicate and silicone paints were formulated with photocatalytic active nanooxides TiO2 and ZnO. Photocatalytic efficiency of coatings was measured as an absorbance change of organic dye Orange II solution at a wavelength of 485 nm. Antimicrobial properties of coatings were tested using agar plate methods. As test microorganisms Pseud. aeruginosa, Esch. coli, Staphyloc. aureus, Penic. chrysogenum and Asperg. niger suspension (density 106 cells/mL) were used. The inhibition effect of tested coatings and inhibitory zones were evaluated after incubation. Coatings containing nanoparticles of titanium dioxide and zinc oxide showed antimicrobial activity against the test microorganisms. Whereas coating with zinc oxide nanoparticles successfully inhibited the growth of both bacteria and fungi, the photocatalytic nanoparticles of titanium dioxide inhibited bacteria but not fungi (weak inhibition was observed).
