Newly Designed DNA Nanorobots Destroy Cancer Tumors

Newly designed DNA nanorobots destroy cancer tumors, according to the study discovered by the Nature Biotechnology journal. The research was conducted by the scientists from the Arizona State University (USA).

published findings explain how the international research team in which Chinese Academy of Sciences (CAS)’s National Center for Nanoscience and Technology was also involved, successfully removed the cancer tumors in mice with the help of programmed DNA to stop a blood supply towards the tumors in them. The process took nearly 24 hours to give impressive results in the melanoma mouse.


Guangjun Nie, a study author stated that, “Our research shows that DNA-based nanocarriers have been shown to be an effective and safe cancer therapy. We are currently working with a biotech firm to translate this revolutionary technology into a viable anti-tumor therapeutic.”

Nanorobots are made up of rectangular, flat DNA origami sheets sized of 60 nanometers by 90 nanometers. Right after getting enclosed with the surface of blood vessels, the nanorobots were programmed to carry its unconscious drug load to the tumor’s heart and expose the enzyme known as thrombin, which is crucial for blood clotting.

Professor and Director, Hao Yan from the Arizona State University said in a statement that, “We have developed the first fully autonomous, DNA robotic system for a very precise drug design and targeted cancer therapy. Moreover, this technology is a strategy that can be used for many types of cancer, since all solid tumour-feeding blood vessels are essentially the same.”
