The invention discloses a fluorescent nano-probe and a preparation method and application thereof in targeting oral and maxillofacial tumors, the CTX-TPD NPs fluorescent nano-probe comprises an amphiphilic
polymer, TPD entrapped by the amphiphilic
polymer and
cetuximab modified outside the amphiphilic
polymer, the amphiphilic polymer is a polymer composed of DSPE-PEG2000 and DSPE-PEG2000-COOH, the amphiphilic polymer is an amphiphilic polymer, the amphiphilic polymer is an amphiphilic polymer, the amphiphilic polymer is an amphiphilic polymer, and the amphiphilic polymer is an amphiphilic polymer. A DSPE part of the amphiphilic polymer is combined with TPD through hydrophobic interaction to form a hydrophobic core of the
nanoparticle, a PEG
chain segment of the amphiphilic polymer is distributed on the outer layer of the
nanoparticle through hydrophilic interaction, and
cetuximab is coupled to carboxyl of the PEG
chain segment of the outer layer of the
nanoparticle. The TPD molecule has breakthrough imaging performance, the AIE characteristic of the TPD molecule is enhanced in
fluorescence in an aggregation state, the ACQ problem of a traditional dye is solved, and the imaging sensitivity is improved.
