Abstract: The bio-synthesis of zinc oxide nanoparticles (ZnO NPs) using aqueous leaf extract of Pisonia grandis is discussed in this work as an effective ecologically beneficial and straightforward method. This strategy intends to increase ZnO nanoparticle usage in the biomedical and environmental sectors, while reducing the particle of hazardous chemicals in nanoparticle synthesis. In the current study, bio-augmented zinc oxide nanomaterials (ZnO-NPs) were fabricated from Pisonia grandis aqueous leaf extracts. Different methods were used to analyze the ZnO-nanoparticles including X-ray diffraction (XRD), Fourier Transforms Infrared (FT-IR), Ultraviolet (UV) spectroscopy, and Field Emission Scanning Electron Microscopy (FE-SEM) with EDX. The synthesized nanoparticles as spheres were verified by FE-SEM analysis; XRD measurements showed that the particle flakes had an average size of 30.32 nm and were very pure. FT-IR analysis was used to validate the functional moieties in charge of capping and stabilizing ZnO nanoparticles. The antimicrobial, cytotoxic, and photodegradation properties of synthesized nanoparticles were assessed using well diffusion, MTT, and UV visible irradiation techniques. The bio-fabricated nanoparticles were proven to be outstanding cytotoxic and antimicrobial nanomaterials. As a result of the employment of biosynthesized ZnO nanoparticles as photocatalytic agents, 89.2% of the methylene blue dye was degraded in 140 min. ZnO nanoparticles produced from P. grandis can serve as promising substrates in biomedicine and applications of environmental relevance due to their eco-friendliness, nontoxic behavior, and cytocompatibility.
