ABSTRACT In this study, Zeolitic Imidazolate Framework‐8 (ZIF‐8) nanomaterials were synthesized using a co‐precipitation one‐pot method that uses ethanol, methanol, and water as solvents for the precursors (2‐methylimidazole Zinc nitrate hexahydrate), resulting in yields of 66.77%, 73.14%, 68.12%, respectively. The as‐synthesized ZIF‐8 thoroughly characterized by X‐ray diffraction analysis, transmission electron microscopy, ultraviolet–visible spectroscopy, Fourier‐transform infrared spectroscopy. analysis showed crystallite size ethanol‐based (24.76 ± 1.67 nm) was smaller than those (26.92 1.89 methanol (31.39 1.03 nm). However, methanol‐based exhibited lower crystallinity (85.93%) water‐based (91.48%) (92.71%). Zeta potential studies revealed had larger surface charge (+37 mV) (+35 or (+24 mV). Transmission microscopy confirmed particle sizes 54.35 2.11 nm ZIF‐8, 57.91 2.26 63.25 4.12 ZIF‐8. Thermogravimetric indicated thermal stability up to 800 °C, with mass losses 55.98% ethanol‐ZIF‐8, 50.12% 65.36% 600 °C. antibacterial studies, largest zone growth inhibition (17.30 0.26 mm) against Escherichia coli compared (15.57 0.32 (14.70 0.20 mm). Pearson's correlation study zeta potential, crystallinity, activity are positively related. Furthermore, minimum inhibitory concentration 50 μg/100 μL, evident cell membrane disruption. Molecular docking experiments ZIF‐8's significant binding affinity E. protein 5AZC, supporting its robust activity.
