The invention discloses a food-borne pathogenic bacterium IFA-IMS detection system based on fluorescent carbon dots and application. The detection system comprises a carbon dot-based bifunctional probe with signal amplification and specific target bacterium recognition capabilities; the immunomagnetic beads can specifically enrich target bacteria. The preparation method comprises the following steps: doping carbon dots into melamino-formaldehyde microspheres to prepare fluorescent microspheres, coupling the fluorescent microspheres to target bacteria (staphylococcus aureus, listeria monocytogenes and escherichia coli) polyclonal antibodies under the action of CuAAC to prepare a carbon dot-based bifunctional probe, and bonding target bacteria monoclonal antibodies to the surfaces of magnetic beads through CuAAC reaction to prepare immunomagnetic beads. An immunomagnetic separation technology, click chemistry and quantum dot microsphere fluorescence labeling are combined.
