Green synthesis and biomedical behavior of Mg-doped ZnO nanoparticle using leaf extract of Ficus religiosa

Abstract

Eco-friendly synthesis of Mg doped ZnO NPs was prepared by Ficus religiosa leaf extract. XRD confirmed the crystalline structure of the prepared Mg-doped ZnO. The functional groups and Zn and O bonding were realized from FTIR and Raman analyses. The surface plasma resonance absorption peak at 363 nm affirmed the formation of Mg–ZnO nanoparticles. The 3.32eV bandgap value of Mg–ZnO NPs was calculated by using Tauc's plot. The photoluminescence spectrum showed the emission behavior and point defect arising from zinc, oxygen vacancies. The hexagonal wurtzite structure of the prepared nanoparticles was observed from FESEM images. From the EDAX study, the elemental compositions have confirmed.The Thermal studies(TG/DTA)study,the Mg doped ZnO Material become thermally stable at 600 °C In XPS spectrum shows good formation of Mg doped ZnO nano materialThe facile synthesized Mg–ZnO NPs using Ficus religiosa leaves showed better antimicrobial properties on gram-positive bacterium, Staphylococcus aureus and fungus, Aspergillus niger . The biomedical behavior of prepared Mg–ZnO NPs was clearly understood from antioxidant(500 μg/mL-87), anti-inflammatory(500 μg/mL-89) and anti-diabetic assays(500μg/mL-82)
