Abstract:

Polypyrrole nanoparticles(NPs) were prepared through iron ion-induced oxidative poly?merization and employed for loading chemotherapy drug gemcitabine, thus producing gemcitabine/polypyrrole composite NPs. The composite NPs indicate strong loading capacity for gemcitabine and good stability in aqueous solution, which reduces the toxicity and side effects of gemcitabine on normal tissues. In addition, the composite NPs have strong absorption in the near-infrared region and can transform the absorbed light energy into heat, acting as an efficient photothermal reagent for tumor photothermal therapy. Meanwhile, the composite NPs are capable to release gemcitabine and perform photothermal-guided chemotherapy. As the reagent with chemo-photothermal combination therapeutic efficacy, gemcitabine/polypyrrole composite NPs can ablate ovarian cancer cells under near-infrared laser irradiation, showing the potential for ovarian cancer therapy.
