Dual-mode colorimetric and fluorescent detection of Staphylococcus aureus using a bacteriophage-modified nanozyme with tetra-(4-aminophenyl) ethylene as a dual-functional substrate.
Herein, a bacteriophage-modified nanozyme sensing platform was developed for dual-mode detection of Staphylococcus aureus in food samples. A peroxidase-like Fe/Ce metal-organic framework nanozyme was functionalized with bacteriophage SAYZU01 to obtain SAYZU01@Fe/Ce MOF, enabling specific recognition and capture of S. a...
