Silver nanoparticles were dispersed on clinoptilolite zeolite. These materials were evaluated as biocides for Escherichia coli and Salmonella typhi. Ag-zeolites were shown to be efficient in eliminating both E. coli and S. typhi present in nutritive media. Particularly, E. coli was eliminated at very short times. In the presence of a zeolite free of silver, bacteria use the zeolite to reproduce rapidly.
