The present invention discloses a preparation method of a biomedical titanium implant with a function of eliminating a surface biomembrane. The method includes the following steps: firstly synthesizing mesoporous polydopamine (MPDA) nanoparticles by a “one-pot method”, constituting a surface-aminated titanium material through diacid corrosion and modification of a 3-aminopropyltriethoxysilane (APTES) coupling agent, and integrating the MPDA nanoparticles into the surface of the titanium material through Michael addition reaction; secondly, taking MPDA anchored on the surface of the titanium material as a photothermal material and a photosensitizer carrier, where MPDA contains abundant aromatic rings capable of facilitating abundant loading of a photosensitizer (indocyanine green, ICG) through π-π stacking interaction; and finally further modifying biocompatible RGD polypeptides on the surface of MPDA by Michael addition reaction, where a modified titanium material is referred to as Ti-M/I/RGD.
