Abstract In this study, zinc sulphide nanomaterial (ZnS NM) powders were prepared with the assistance of an atmospheric pressure soft jet plasma (APPJ) device. Regular approaches to ZnS preparation mainly resulted in aggregated powders, thus plasma methods were investigated to obtain controlled morphological structures. The APPJ plasma-assisted ZnS exhibited unique surface architectures, such as nanorods, layers and spherical aggregates, that were controllably obtained by changing the reactant concentration and type of precursor. The prepared ZnS showed good thermal stability by no changes in its composition up to 400 °C. The APPJ plasma-assisted ZnS showed sphalerite and wurtzite crystal structures and resulted in excellent chemical purity. The simple and handy APPJ plasma method shows good potential for shape-controlled ZnS NMs preparation without addition of surfactant chemicals, mechanical stirring, external heating or any other tedious procedures. This capability showcases the scientific and technological merit of this technique. The prepared ZnS NMs were utilized as antibacterial agents and evaluated the activity using three techniques against the human pathogens of E. coli, S. aureus and K. pneumoniae. The ZnS NMs showed effective concentration and shape-dependent activity when used as an antibacterial material.
