Título: | Glass-(nAg, nCu) biocide coatings on ceramic oxide substrates |
Autor: | Esteban-Tejeda, Leticia CSIC; Malpartida Romero, Francisco; Díaz, Luis A. CSIC ORCID; Torrecillas, Ramón CSIC ORCID CVN; Rojo, Fernando CSIC ORCID ; Moya, J. S. CSIC | Fecha de publicación: | 2012 | Editor: | Public Library of Science | Citación: | PLoS ONE 7(3): e33135 (2012) | Resumen: | The present work was focused on obtaining biocide coatings constituted by a glassy soda-lime matrix containing silver or copper nanoparticles on ceramic (alumina and zirconia based) substrates. Both glassy coatings showed a high biocide activity against Gram-, Gram+ bacteria and yeast, reducing cell numbers more than three logarithms. Silver nanoparticles had a significantly higher biocide activity than copper nanoparticles, since the lixiviation levels required to reduce cell numbers more than 3 logarithms was of almost 1-2 μg/cm 2 in the case of silver nanoparticles, and 10-15 μg/cm 2 for the copper nanoparticles. | Versión del editor: | http://dx.doi.org/10.1371/journal.pone.0033135 | URI: | http://hdl.handle.net/10261/50401 | DOI: | 10.1371/journal.pone.0033135 | Identificadores: | doi: 10.1371/journal.pone.0033135 issn: 1932-6203 |
