    Biosynthesis, characterization, and antimicrobial study of zinc oxide nanoparticles using Adonida merrilli leaf extract

    The utilization of plant-mediated methods to synthesize metal oxide nanoparticles (NPs) is becoming increasingly popular due to its simplicity, low cost, and environmental friendliness. Adonida merrilli leaf extracts in aqueous form were used for the production of nanoparticles of zinc oxide (ZnO). scanning electron microscope with energy dispersive X-ray (SEM-EDX), Fourier transform infrared spectrometer (FTIR), X-ray diffractometry (XRD), and UV-Vis spectrophotometer were accustomed to analyze the ZnO nanoparticles. The antibacterial effects of the ZnO NPs was examined on pathogens such Salmonella, Candida, Escherichia coli, Staphylococcus aureus, and Pseudomonas aeruginosa.XRD indicate spherical crystalline nanoparticles with an average particle size of 73.82 nm. Zinc oxide nanoparticle absorption wavenumber at 715 cm-1 was seen in the FTIR, and EDX chemical mapping confirms the elemental composition of zinc and oxygen. For Candida, Salmonella, Pseudomonas aeruginosa, Escherichia coli, and Staphylococcus aureus measured Zones of Inhibition (ZI) values are 30.00, 36.00, 32.00, 40.00, and 36.00 mm, and the measured Minimum Inhibitory Concentration (MIC) values are 7.81, 1.95, 7.81, 1.95, and 3.90 mg/mL, respectively. The results of this investigation, as shown by the MIC and ZI values, point to the possible use of Adonida merrilli extract in the synthesis of highly crystalline Zinc oxide nanoparticles (ZnONPs) as an alternative medication.
