Green Sythesis of Zinc Oxide Nanoparticles from Clitoria ternatea Extract: Dual Functionality in Arsenic Adsorption and Antibacterial Applications in Arsenic Adsorption and Antibacterial Applications

The synthesis of zinc oxide nanoparticles (ZnO NPs) using Clitoria ternatea flower extract offers a sustainable and environmentally friendly approach for a range of versatile applications. This study highlights the dual functionality of these biosynthesized ZnO NPs, focusing on their effectiveness in both arsenic adsorption and antibacterial activity. The green synthesis process involves extracting ZnO NPs from Clitoria ternatea flower extract, followed by detailed characterization using advanced analytical techniques. These include field emission scanning electron microscopy (FESEM), X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), and zeta potential analysis, all of which confirm the successful production of ZnO NPs with the desired properties. The antibacterial activity of the ZnO NPs was tested against Staphylococcus aureus and Pseudomonas aeruginosa, revealing strong bactericidal effects. These effects are largely attributed to the nanoparticles' small size and unique structural properties. Furthermore, both qualitative and quantitative analyses of arsenic adsorption demonstrate the ZnO NPs' efficiency in removing arsenic from solutions, underscoring their potential in water treatment applications. In conclusion, this green synthesis approach represents a promising strategy for producing multifunctional ZnO NPs with broad applications in environmental remediation and the biomedical field.
