The scientific field devoted the importance of studying nanotechnology, which characterizes nanoparticles and their multi-purpose functions, especially nanomedicine techniques. The review focused on newer technologies in biomedical applications as a drug vector in cancer treatment. To occupy the center stage on most of the biological vectors of drugs for the treatment of cancer. Practically, chemical treatments have harm as they target cancerous and non-cancerous cells alike, the solubility is almost non-existent, and the inability of chemotherapy to penetrate cancerous cells, which opens the way for this technique with clear prospects for the aforementioned purpose. The ability to selectively deliver nano-drugs to targeted cancer cells in an optimal manner and to avoid non-specific interactions with healthy cells. The current review focuses on ways to improve the size, shape, and properties of nanomaterials that can be exploited in cancer therapy. The successful treatment of nanocarriers for cancer can be designed for the future as nanotherapies.
