Disclosed in the present invention are an acid-responsive nano-micelle on the basis of the Cherenkov effect, and a preparation method and use therefor. The nano-micelle uses pyropheophorbide a as the photosensitizer main body, and modifies N,N-diisopropylamine, 131I labeled tyrosine or any one of 68Ga, 177Lu, 89Zr labeled tetraazacyclododecane tetraacetic acid, and polyethylene glycol to functionalize, and connects by means of N-Alpha-Fmoc-N-Epsilon-t-Boc-L-Lysine.
