Cancer have gotten another enemy i.e DNA nanobots

Researchers from Wyss Institute have successfully done the experiments of "DNA nanorobots" to treat cancer. They have found some toxic effects but those were less than other materials would do.

Researchers have used aptamers for particular targeting and payloads such as drug molecules to treat the cancer.

Researchers considered immune system of human beings, so that robots work just like that of white blood cells targeting blood cells. Then the researchers tested the robots on several cultures of cancerous cells such as leukemia and lymphoma, with corresponding payloads of antibodies. 

According to researchers, the robots caused some problems of toxicity but those problems were fewer than many materials and chemicals would have.

"We can finally integrate sensing and logical computing functions via complex, yet predictable, nanostructures -- some of the first hybrids of structural DNA, antibodies, aptamers and metal atomic clusters -- aimed at useful, very specific targeting of human cancers and T-cells," said George Church, Ph.D., a Wyss core faculty member and Professor of Genetics at Harvard Medical School, who is Principal Investigator on the project.

From Wyss Institute,

Because DNA is a natural biocompatible and biodegradable material, DNA nanotechnology is widely recognized for its potential as a delivery mechanism for drugs and molecular signals. But there have been significant challenges to its implementation, such as what type of structure to create; how to open, close, and reopen that structure to insert, transport, and deliver a payload; and how to program this type of nanoscale robot.
