Objectives:
To evaluate the contributions of the some quantum dots in different biological uses in order to valorizes such nanomaterials for further applications.
Methods:
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) spectroscopies. Zinc sulfide nanoparticles were screened for their antibacterial and antifungal profiling and tested for antioxidant activity using 1,1-diphenyl-2-picrylhydrazyl (DPPH), hydroxyl radical (OH) and hydrogen peroxide (H2O2) scavenging activity, ferric reducing power (FRP) assay and ferrous ion chelating (FIC) methods.
Results:
The sizes of the crystallites were estimated to 3 nm using the Debye-Scherrer formula based on the XRD data. The shape was identified to be quasi-spherical with agglomerated particles. The obtained ZnS quantum dots present an antioxidant activity especially in oxido-reduction power, and can be used for species profiling either for bacteria and fungus.
Conclusion:
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.
