摘      要：Objective:To evaluate the contributions of the some quantum dots in different biological uses in order to valorizes such nanomaterials for further ***:Zinc sulfide ZnS nanoparticles were synthesized in aqueous medium at pH constant,the obtained nanoparticles has been characterized by X-ray diffraction(XRD),transmission electron microscopy(TEM)and Fourier Transform Infra-red(FTIR) *** sulfide nanoparticles were screened for their antibacterial and antifungal profiling and tested for antioxidant activity using l,l-diphenyl-2-picrylhydrazyl(DPPH),hydroxyl radical(OH·) and hydrogen peroxide(H_2O_2) scavenging activity,ferric reducing power(FRP) assay and ferrous ion chelating(FIC)***:The sizes of the crystallites were estimated to 3 nm using the DebyeScherrer formula based on the XRD *** shape was identified to be quasi-spherical whith agglomerated *** obtained ZnS quantum dots present an antioxidant activity especially in oxido-reduction power,and can be used for species profiling either for bacteria and ***:It was found that ZnS nanoparticles showed relatively higher antioxidant activities and antibacterial with an antifungal behavior which proves that this nanomaterials can react at the interface with the life entities.
