Conventional chemotherapy and radiotherapy have become crucial first-line clinical treatments for cancer. However, along with their wide usage, limited therapeutic effects, severe adverse reactions, unaffordable costs, and complicated operations lead to failures of these treat- ments. Moreover, the emergence of multidrug resistance inhibits the longtirne usage of chemotherapeutics. One of the major causes of treatment failure is the insufficient sensitivity of cancer cells to therapeutic drugs or treatments. With the rigorous development of nanotechnolog~ tailored nanoparticles can efficiently sensitize malignant cells by inducing intracellular structural and functional changes, which could affect vital intracellular processes such as metabolism, signal conduction, proliferation, cell death as well as intracellular drug delivery. Here, we review recent advances in nanomaterial-assisted sensitization of oncotherapy, and challenges and strategies in the development of nanomedical approaches.展开更多
