DNA robots can kill cancer cells

On February 22nd, the famous "Science" magazine of the United States said scientists from Harvard University (USA) have successfully made robots completely from the strands of DNA. This special robot is programmed to receive commands and carry antibodies to destroy diseased cells in the human body.

DNA is a nucleic acid (Deoxyribonucleic acid) that contains genetic information for the development and function of living cells. The tiny, nanoparticle shell DNA nanoparticles can receive antibodies from the immune system that cause cells to self destruct.

Harvard University scientists say the next step will be in animals. DNA robots are tuned to extend blood flow to locate cancer cells. When all cancer cells are detected or destroyed or reprogrammed as normal cells, cancer is completely cured.

The DNA robot concept simulates the activity of immune cells in the human body. These cells identify viruses or strange invaders and attack them. A similarly potent DNA robot can pave the way for the development of new therapies against cancer without affecting the healthy cells of the human body.

In addition to cancer, DNA robots can be used in the treatment of autoimmune diseases because they can be programmed to find immune cells that attack the wrong way in the human body and reprogram these immune cells. .
