Bimetallic Gold–Platinum (AuPt) Nanozymes: Recent Advances in Synthesis and Applications for Food Safety Monitoring

The growing global demand for rapid, sensitive, and cost-effective food safety monitor- ing has driven the development of nanozyme-based biosensors as alternatives to natural enzyme-based methods. Among various nanozymes, bimetallic gold–platinum (AuPt) nanozymes show superior catalytic performance compared to monometallic and other Au-based bimetallic hybrids. This is due to their synergistic colorimetric, catalytic, geo- metric, and ensemble properties. This review systematically evaluates...
