Summary: | The invention discloses a super-resolution three-color fluorescence co-localization method for high-precision analysis of exosome phenotypes. According to the method, fluorescence signals generated due to non-specific adsorption can be removed; according to the method, three-color fluorescent labeling, three-color super-resolution imaging and pixel counting of a target exosome are combined, the pixel counting method is realized through MATLAB, and non-specific binding sites can be eliminated on the single-pixel level; in addition, the method also realizes spectrum identification of the exosome membrane protein. 3D phenotype information of various exosomes is obtained by marking three specific proteins; according to the method, different types of exosomes are classified according to protein expression levels; by using the SMLM microscope and the pixel counting method, the detection reliability can be improved to the maximum extent.
