Abstract:
We succeeded in producing pure and magnesium-doped zinc oxide nanoparticles (Mg-Zn NPs) by making use of a Prosopis farcta leaf extract and subsequently distinguished the quality of our NPs with the use of field energy scanning electron microscopy (FESEM), energy-dispersive X-ray (EDX), powder X-ray diffraction (PXRD), and UV-vis. In correlation to our observations, the particulates were spherically produced at a size of 20 nm with the ability to cause antimicrobial impacts on Streptococcus mutans bacteria and Candida albicans fungi. Inhibition zones of 18 ± 0.3 and 24 ± 0.3 mm were obtained for 5% Mg-Zn NPs against bacteria and fungi, respectively. Based on these results, our work suggests a practicable proposition for our synthesized product to be considered as a worthy alternative for dental and oral utilizations.
