CeO 2 nanoparticles used to repel biofilm formation (before): LEGO brick treated with commercial polyurethane lacquer (l.) and with polyurethane lacquer containing CeO 2 nanoparticles (r.)
Cerium dioxide nanoparticles work in biological processes like natural enzymes and change signaling molecules, thereby preventing the formation of biofilms. CeO 2 nanoparticles used to repel biofilm formation (before): LEGO brick treated with commercial polyurethane lacquer (l.) and with polyurethane lacquer containing CeO 2 nanoparticles (r. October 2022 Bacteria love moist surfaces. Once they have settled there, they do not live as solitary organisms but form larger communities that are embedded in a protective film. These biofilms are found on various surfaces, for example at home on light switches, in the bathroom, on toys or keyboards, on shopping carts or ATMs that many people touch with their hands. This can lead to contact infections. The bacteria, such as the pathogenic bacterium Pseudomonas aeruginosa, are often persistent and defy the body's own immune system or chemical biocides.
