CSIC | Fecha de publicación: | 2015 | Editor: | Public Library of Science | Citación: | PLoS ONE 10(7): e0132709 (2015) | Resumen: | A new family of non-toxic biocides based on low melting point (1250°C) transparent glasses with high content of ZnO (15–40wt%) belonging to the miscibility region of the B2O3-SiO2-Na2O-ZnO system has been developed. These glasses have shown an excellent biocide activity (logarithmic reduction >3) against Gram- (E. coli), Gram+ (S. aureus) and yeast (C. krusei); they are chemically stable in different media (distilled water, sea-like water, LB and DMEN media) as well as biocompatible. The cytotoxicity was evaluated by the Neutral Red Uptake using NIH-3T3 (mouse embryonic fibroblast cells) and the cell viability was >80%. These new glasses can be considered in several and important applications in the field of inorganic non-toxic biocide agents such as medical implants, surgical equipment, protective apparels in hospitals, water purifications systems, food packaging, food storages or textiles. | Versión del editor: | http://dx.doi.org/10.1371/journal.pone.0132709 | URI: | http://hdl.handle.net/10261/137373 | DOI: | 10.1371/journal.pone.0132709 | Identificadores: | doi: 10.1371/journal.pone.0132709 issn: 1932-6203 |
