Cancer is one of the deadliest diseases of this century. Tedious and painful radiation therapy and chemotherapy are administered using many drugs including antitumor antibiotics, which cause a lot of side effects. As an alternate, DNA nanorobots serve as a potential cancer treatment technique which is very much safer than other therapies and acts specifically as well. DNA nanobots are said to set a new milestone in the development of medical studies. The primary objective of this bot is to target and eliminate cancer cells from the human body. These bots are made of a single strand of DNA folded into the desired shape. The bots will have two states-an “off” position, where the clamshells are closed tightly to bypass healthy cells without any damage and an “on” position, where the clamshell opens up to expose cancerous cells to the drug so that the drug can do its job to eliminate the cancer cell. This novel idea will be actively used within the public when it passes its first human trial. In this review, we focus on eliminating cancer cells. Since the bot can be programmed and is capable enough to carry a payload, it can also be used to cure any other diseases as a secondary target. Creation of nanobots has been under progress already and may come within the public after an estimated time of 5 years.
