A disease is one of the secret powers, which could cause a disaster to the human civilization, but at the same time promote the fast development of science and technology. As one of the typical diseases, cancers have become a leading cause of death worldwide. According to the International Agency for Research on Cancer, approximately 14.1 million new cases of cancer occurred globally, which caused about 8.2 million deaths in 2012 (Stewart and Wild 2014). Cancer is defi ned as a group of diseases, which are featured by rapid creation of abnormal cells which can grow beyond their boundaries. In order to solve the problem, various methods including chemotherapy, radiation, surgery, palliative care, and immunotherapy are utilized, which bring serious side-effects, or can not completely defeat the disease. With the development of nanoscience and nanotechnology, controlled drug release (CDR) systems bring new hope for managing the problem.
