Nano drug have high targeting property and slight adverse reaction，and it is becoming one of the hot spots in targeting treatment of ovarian cancer. The application of nano durg in the ovarian cancer includes targeted chemotherapy，targeted gene therapy，targeted radiation and so on. At present，the application of nano drug in ovarian cancer is still in the initial stage，but we believe that it will play an important role in the treatment of ovarian cancer.
