Scientists at the China Center for Nanoscience and Technology claim that they have created and tested the world's first autonomous DNA nanorobots capable of successfully resisting malignant tumors. Each such nanorobot is very small and cannot be seen with the naked eye. The nanobot is 5,000 times smaller than the tip of a needle, according to the Xinhua news agency.
The DNA-based robot has a tubular structure and is only about 90 nanometers long. The baby's diameter is 19 nanometers. Thanks to their design, nanorobots will help conduct research and will independently find tumors, and then block the blood supply to the malignant neoplasm. After that, the tumor will begin to disintegrate in a few weeks or even days - such results were obtained by a team of researchers during testing of new robots. Nanorobots were injected into mice, and the results showed a significant reduction and often complete tumor regression within a few days or weeks.
According to scientist Zhao Yuliang, the research team has also conducted extensive research into the safety of nanorobots, including the miniature pig Bam, which is physiologically and anatomically similar to humans.
“Unlike chemotherapy and radiation, DNA nanorobots are able to heal tumors without harming the surrounding healthy tissue. Nanorobots do not accumulate in the brain and thus do not pose a risk of stroke,”Zhao said.
Scientists are now conducting preclinical studies and are hoping to translate this revolutionary technology into a viable cancer therapy.
