Green Synthesis of CuO/MgO Nanocomposites Using Mangifera indica Leaf Extract: Characterization and Biological Applications

Bimetallic nanocomposites have emerged as an important impact innovative material in recent times. We propose the green biological synthesis of bimetallic Copper/Magnesium (Cu/Mg) nanocomposites by incorporating an aqueous extract of Mangifera indica leaves, in response to increasing interest. A broad spectrum of analytical strategies, including UV-vis, FTIR, TEM, XRD, XPS, TGA. The UV–vis spectrophotometer (UV-vis) gave the maximum absorbance at 205 and 257 nm range. The Fourier transform infrared spectroscopy (FTIR) analysis identified active elements in the leaf extract that they functioned as surfactant compounds, stabilizers, capped molecules, and reducing agents, Transmission Electron Microscopy (TEM), were used to determine the optical property and surface morphology of the nanoparticles. whereas TEM image revealed that the material particle size was 20-50 nm. X-ray diffraction (XRD) analysis revealed that the sample that was produced was polycrystalline, with an average particle size of around 37.01 nm.The formation of a CuO/MgO heterojunction has been demonstrated by X-ray photoelectron spectroscopy (XPS) results, which were consistent with TEM and XRD observations.The Thermogravimetric Analysis(TGA) and Derivative Thermogravimetry (DTG) curves show the thermal behaviour of the synthesized CuO/MgO NCs. The bimetallic nanocomposites (Cu/Mg) demonstrated potential antibacterial and anti-fungal potency, with comprehensive analyses which are provided in detail. The agar well diffusion method was implemented to assess the antimicrobial effectiveness of the copper/magnesium nanocomposites. According to the findings, Mangifera indica leaf extract displays potential antimicrobial activity at various concentrations, ensuring the presence of bioactive substances that are beneficial in medical applications.
