In the field of medicine, the application of nanotechnology is gradually changing our approach to diagnosing and treating diseases. In recent years, medical nanorobots, as an innovative technology with great potential, have attracted extensive attention from scientists at home and abroad. This article will introduce to you the latest research progress in medical nanorobots, as well as related drugs and devices that have passed FDA certification.
What are medical nanorobots? Medical nanorobots are tiny robots made using nanotechnology, with sizes around the nanometer scale (1 nanometer = 10^-9 meters). Due to their extremely small size, nanorobots can move freely inside the human body, achieving precise diagnosis and treatment of diseases.
Recent research progress in China: In recent years, China has made a series of important breakthroughs in the field of medical nanorobots. Top domestic research institutions such as the Chinese Academy of Sciences, through interdisciplinary cooperation, have successfully developed a number of medical nanorobot products with independent intellectual property rights. For example, the research team of the Shanghai Institute of Technical Physics, Chinese Academy of Sciences, invented a tumor cell-targeted treatment system based on nanomotors. This system uses nanorobots to release anticancer drugs on the surface of tumor cells to achieve precise treatment of cancer. Studies have shown that this type of nanorobot has shown significant therapeutic effects in animal experiments.

Recent research progress abroad: Internationally, research in the field of medical nanorobots has also achieved a series of important results. Research teams in the United States, Europe, and other countries, combining cutting-edge technologies in biology, materials science, and other fields, have carried out a number of innovative studies. In 2018, scientists from the California Institute of Technology invented a DNA nanorobot. The robot, made of DNA, has autonomous walking and carrying functions. Researchers have achieved precise treatment of tumor cells by loading anticancer drugs into the nanorobot. Drugs and devices certified by the FDA: Although medical nanorobot technology is still in its development stage, some related products have passed the certification of the U.S. Food and Drug Administration (FDA) and entered clinical applications. In 2015, the FDA approved a nano medical device called "NanoTherm". This device uses nano magnetic particles for tumor treatment, heating through high-frequency magnetic fields, causing heat damage to tumor cells and leading to apoptosis. NanoTherm has achieved significant clinical effects in the treatment of brain tumors and other fields. In addition, some nano drug delivery systems have also been certified by the FDA, such as doxorubicin liposomes (Doxil) and paclitaxel liposomes (Abraxane). These nano drug delivery systems encapsulate anticancer drugs, improve the stability of drugs in the body, reduce side effects, and thus improve therapeutic effects.
Prospects for medical nanorobots: Medical nanorobot technology still faces many challenges, including improving the stability of nanorobots in the body, reducing toxicity, and improving manufacturing efficiency. However, with scientists' in-depth research in the fields of nanotechnology, biology, materials science, and other fields, medical nanorobots will continue to bring us more amazing innovative results. In the future, medical nanorobots are expected to achieve more precise diagnosis and treatment of diseases, bringing new treatment options for various diseases such as cancer, neurological diseases, infectious diseases, etc. It will open a new chapter in the development of modern medicine and bring better quality of life to patients worldwide. In summary, as a promising innovative technology, medical nanorobots are leading a new revolution in the field of medicine, opening up a broader prospect for the cause of human health. We have reason to expect that with the continuous progress of science and technology and the deepening of international cooperation, medical nanorobots will bring a better future to patients worldwide.
