Microbial contamination is a tremendous problem in our society nowadays. ZnO is extensively used as a universal inorganic antibacterial reagent in the food industry, however, few reports related to antibacterial function of ZnS have been published up to date.

The obtained ZnS nanospheres exhibited high performance in prohibiting the growth of the foodborne pathogen Escherichia coli and negligible mammalian cell toxicity.
