The invention belongs to the technical field of biological nano-magnetic bead application and medical testing, and relates to a fluorescent coded magnetic bead and its preparation and application. At least four fluorescent signal molecules and one recognition molecule I with different wavelengths, the fluorescent-encoded magnetic beads can recognize target molecules through specific binding, and use fluorescence as a reporter signal to achieve simultaneous, high-throughput detection of multiple target molecules , simplifies the detection process, the preparation process of the magnetic microspheres of the present invention is simple, the prepared magnetic microspheres are regular in shape, uniform in size distribution, and good in dispersion, and the fluorescently encoded magnetic beads of the present invention can be used for flow cytometry Analytical and LC chip inspection to automate inspection techniques and combine with artificial intelligence. |
