Fluorescence detection chip, fluorescence detection system, fluorescence detection method and application thereof

A fluorescence detection chip, comprising:

• an upper casing and a lower casing;
• a sample cell for collecting a sample to be detected and lysing the sample to be detected;
• a mixed liquid cell connected to the sample cell through a first micro-channel and used for extraction of target fragments from the lysed sample to be detected;
• a waste liquid cell connected to the mixed liquid cell, and used for collecting a waste liquid generated during the extraction of the target fragments;
• and
• a number of independent reaction detection cells connected to the mixed liquid cell through a second micro-channel and used for fluorescent detection of the target fragments, wherein the reaction detection cells have cell walls made of a superconducting thermal material;
• wherein the sample cell, the mixed liquid cell, the waste liquid cell and the reaction detection cells are all arranged in the lower casing, and a number of sample inlets are provided on the upper casing, which correspond to the sample cell, the mixed liquid cell and the reaction detection cells, respectively.
