Iron loaded EMT nanosized zeolite with high affinity towards CO 2 and NO

Résumé

The preparation of iron-loaded nanosized zeolite with EMT-type structure (Fe-EMT) is reported. The sorption capacity of the Fe-EMT zeolite crystals for NO and CO2 is evaluated. The application of Fe-EMT zeolite as a gas delivery system with high capacity for CO2 and NO in biomedicine is considered. Therefore the toxicity of the pure EMT and Fe-EMT zeolite nanocrystals is studied. Primary culture of astrocytes was exposed to zeolite nanocrystals. In addition, two human cell lines, U87-MG glioblastoma and HEK-293T were used. Cells were exposed to zeolites nanocrystals with concentrations of 50, 100 and 400 μg/ml for 24 h and 48 h. Cytotoxicity was assessed by a cell viability assay and no alteration of cell viability exposed to zeolite nanoparticles was observed.
