The invention relates to the technical field of composite nano materials, in particular to a preparation method and application of a ferrocenyl photo-thermal nano material, and the preparation method comprises the following steps: S1, preparing gamma-3-chloropropionyl-L-glutamate which is marked as CPLG; s2, preparing gamma-3-chloropropionyl-L-
glutamic acid N-
carboxylic acid anhydride, and recording the gamma-3-chloropropionyl-L-
glutamic acid N-
carboxylic acid anhydride as CPLG S3, preparing methoxy
polyethylene glycol-b-poly (gamma-3-azidopropionyl-L-
glutamic acid ester), and recording the methoxy
polyethylene glycol-b-poly (gamma-3-azidopropionyl-L-glutamic acid ester) as mPEG-b-PAPLG; s4, preparing mPEG-block-poly (gamma-3-
ferrocene propionyl-L-glutamic acid ester), and recording the mPEG-block-poly (gamma-3-
ferrocene propionyl-L-glutamic acid ester) as MPF ( S5, preparing the ferrocenyl photo-thermal nano material; the prepared
ferrocene-based photo-thermal nano material is used for photo-
thermal therapy of tumors, an amphiphilic
polymer and
acetylene ferrocene are used for carrying out a click
chemical reaction, the nano material has a nano particle core with higher hydrophobicity, leakage of an organic
photosensitizer in the nano material can be effectively prevented, the nano material can cope with a complex in-vivo environment, and the photo-
thermal therapy effect is improved.
