Extensive use of magnetic iron oxide (magnetite) nanoparticles (IONP) has raised concerns about their biocompatibility. It has also stimulated the search for its green synthesis with greater biocompatibility. Addressing the issue, this study investigates the molecular nanotoxicity of IONP with embryonic and adult zebrafish, and reveal novel green fabrication of iron oxide nanoparticles (P-IONP) using medicinal plant extract of Phyllanthus niruri. The synthesized P-IONP was having a size of 42 ± 08 nm and a zeta potential of −38 ± 06 mV with hydrodynamic diameter of 109 ± 09 nm and 90emu/g magnetic saturation value. High antibacterial efficacy of P-IONP was found against E.coli. Comparative in vivo biocompatibility assessment with zebrafish confirmed higher biocompatibility of P-IONP compared to commercial C-IONP in the relevance of mortality rate, hatching rate, heart rate, and morphological abnormalities. LC₅₀ of P-IONP and C-IONP was 202 μg/ml and 126 μg/ml, respectively. Molecular nano-biocompatibility analysis revealed the phenomenon as an effect of induced apoptosis lead by dysregulation of induced oxidative stress due to structural and functional influence of IONP to Sod1 and Tp53 proteins through intrinsic atomic interaction.
