Abstract The green synthesis of Iron oxide nanoparticles (IONPs) has shown numerous advantages over conventional physical and chemical methods as these non-ecofriendly uses toxic chemicals complicated equipments. In present study, were created using simple, sustainable, eco-friendly chemistry protocol. roots novel medicinal plant Sageretia thea was used a bio-template for the preparation IONPs. Further, IONPs confirmed different analytical tools like UV-Vis, FT-IR, XRD, EDX, SEM. average sizes (NPs) found to be 16.04 nm. asynthesized evaluated several biological potentials including antibacterial, antifungal Anti-radical (DPPH) cytotoxicity assays. Antibacterial potencies investigated bacterial strains (in concentration range 1000–31.25 µg/mL) revealing significant antibacterial potentials. ABA SAU reported least susceptible while KPN observed most strain in bactericidal studies. fungal investigate revealed strong against pathogenic strains. Furthermore, MRA, FA ANI fungicidal examination. Significant potential examined brine shrimps assay, thus cytotoxic IC 50 S. based recorded 33.85 µg/mL. Strong anti-radical assay performed evaluate ROS scavenging S.T@IONPs. highest noted 78.06%, TRP 81.92% TAC 84% on maximum 200 summary, our experimental results concluded, that have antifungal, DPPH can applications. nutshell, as-prepared bioactivities we recommend, other vitro vivo further analyze
