Nanorobots in Cancer Therapy

Abstract

Cancer is treated effectively by means of currently available medical knowledge and equipment for therapy. Still, earlier diagnosis of cancer is a crucial factor to determine the probabilities of a cancer patient for survival. Cancer must be identified at least before the stage of metastasis. Another significant aspect is the develop an efficient targeted drug delivery system, which can reduce the occurrence of side effects for achieving an effective patient therapy. Nanomedicine approach can be utilised for diagnosis, treatment and preventing various diseases by using molecular tools and molecular knowledge of human body. By using nano-structured materials and simple nanodevices which can be manufactured, nanomedicine can address various medical problems. Within few decades’ technology assisted medicine and particularly robotics will have a significant impact. Surgeon’s motor performance, diagnosis capability etc. can be augmented by robots. Nanorobots can navigate as blood borne devices and thus it has an extremely important role in treatment of cancer. For diagnosing of cancerous cell inside the patient’s body at its earlier development stages, chemical biosensor embedded nanorobots can be used. To determine the E-cadherin signals intensity, integrated nanosensors may be utilized. The aim of the present article is to explore the future nanorobotic’s use to fight cancer and, their designing and architecture.
