Engineering Nano‐Pills to Inhibit Ovarian Cancer Proliferation and Migration through a Combination of Chemical/Nucleic Acid Therapy

Ovarian cancer (OC) is the most fatal of all gynecological malignancies, presenting a significant threat to women's health. Its treatment is complicated by severe dose-dependent chemotherapy toxicity, drug resistance, and tumor migration. Herein, an intelligent combination strategy of chemotherapy and nucleic acid therapy, named ApMEmiR&D is developed. This integrated system consists of three parts: the nano-pill, the protective membrane, and the navigation element. Nano-pills are nanospheres assembled from miRNA and doxorubicin (DOX) with the help of ferrous ions (Fe
