Abstract:

Polydopamine(PDA) nanoparticles were prepared with ethanol and ammonia in water, which performed an excellent light-heat energy conversion ability. An anti-cancer medicine, doxorubicin(Dox), was loaded on the surface of the polydopamine nanoparticles efficiently through π-π stacking and covalent bond, and then the doxorubicin loaded polydopamine(PDA-Dox) nanoparticles were prepared. The drug delivery property of the materials was studied. As a result, the drug release behavior could be controlled by the pH value of the environment, which was improved in acidic condition. When the PDA-Dox nanoparticles were exposed to the laser irradiation, the cancer cell, HeLa, could be killed efficiently by the materials through the chemo-photothermal synergistic therapy. Combined with the laser irradition, the nanomaterial could kill the cancer cell efficiently with the synergistic therapy between the phototherpy and chemotherapy in vitro.

Key words: Polydopamine nanoparticle, Doxorubicin, Chemotherpy, Photothermal therpy
