Zusammenfassung: | A pharmaceutical composition includes one or a plurality of metal nanoparticles and therapeutic agent. Each of the metal nanoparticles includes a core and a stabilizing agent covering the surface of the core. The therapeutic agent is attached to the stabilizing agent of the metal nanoparticles. The therapeutic agent is an amphiphilic compound and has at least one hydrophobic chain interacting withthe stabilizing agent. The pharmaceutical composition may further include a polymer shell encapsulating the metal nanoparticles and the therapeutic agent for enabling controlled release of the therapeutic agent. The pharmaceutical compositions are bifunctional and may be used for diagnosing and treating cancer. A preparing method utilizing the pharmaceutical composition and uses of the composition are also provided.
