Micro and Nano Robotics-assisted Targeted Drug Delivery, Surgery and Radiotherapy for Cancer Treatment

Cancer refers to the progressive abnormal cell growth with the potential to invade or spread to other parts of the body. Many cancer therapies continue to be based on systemic chemotherapy along with radiation therapy. Numerous nanomedicine strategies have been developed to address the untargeted nature of these therapies and the serious side effects they can cause. As targeted therapeutic delivery is still difficult, engineered robots and microrobots are getting more and more attention and applicability. Microrobots can more effectively reach malignancies because of their unique features and functions, like their motility, which allows them to penetrate malignant tissues. Modern cancer treatment techniques built on information technology can boost patient compliance and improve patient survival. The delicate tissue can be overly damaged by radiation and surgery, and most chemotherapy medications are unable to penetrate the blood-brain barrier and reach the tumor. Cancer prevention, its early detection, quick diagnosis, and prompt treatment are very crucial. Robotic technology is employed in a variety of medical settings, and its applications in surgery have evolved that have an impact on the field of cancer treatment as well. A key improvement in cancer therapy with the aid of robotics would be the ability to target and deliver medications directly to the tumor.
