Abstract The pursuit of environmentally sustainable and potent antimicrobial agents has spurred the investigation innovative nanocomposite materials, leading to development cefazolin‐loaded magnesium oxide/polyethylene glycol (CFZ@MgO/PEG NC) nanocomposites. This research encompasses biosynthesis using Laurus nobilis L. extract, resulting in nanocomposites with a size distribution approximately 35 nm. XRD analysis revealed an average crystallite 37 ± 0.9 nm for CFZ@MgO/PEG NC. antibacterial efficacy demonstrated dose‐dependent inhibition zones, NC achieving zones 19 mm, 14.5 14 mm against Pseudomonas aeruginosa , Escherichia coli Staphylococcus aureus respectively, at 5 mM concentration. In vivo toxicity studies albino rats indicated changes biochemical parameters, such as increase urea levels 0.75 0.12 mmol/L creatinine 5.55 0.3 µmol/L 400 µg/mL dosage. MgO/PEG exhibited notable anticoagulant properties, comparable EDTA, emphasizing its potential blood coagulation management. These findings highlight promising agent, therapeutic applications requiring careful dosage optimization mitigate toxicity.
