<b>Rapid Colorimetric Detection and Potent Eradication of Staphylococcus aureus in Dairy Products via a Dual-Functional Magnetic Mesoporous MnOₓ Nanozyme Probe</b>

<p dir="ltr">Staphylococcus aureus (S. aureus), a major foodborne pathogen contaminating dairy products, threatens food safety and public health via food poisoning and severe infections like bacteremia. Conventional culture-based methods are time-consuming, while advanced techniques need expensive equipment, limiting on-site use. The probe exhibited high specificity, with no response to interfering bacteria, and demonstrated good applicability in spiked milk (recovery: 82.1% – 90.5%, RSD < 5%). Preliminary tests confirmed Mag-MnOx’s significant bacteriostatic activity against S. aureus. This low-cost, easy-to-operate strategy enables S. aureus detection and elimination, promising on-site use in food safety and clinical diagnosis.</p>
