The "nanobots" in science fiction movies have now become a reality. According to CCTV reports, recently,The latest 3D micro-nano robot developed by the Institute of Physics and Chemistry of the Chinese Academy of Sciences has made it possible for nano-doctors to drill into the body to treat diseases.
This little robot looks like a small clip.The size is only about 40 microns, which is thinner than a human hair.. This clamp is actually a pair of flexible "robot hands" that can complete precise tasks such as grabbing cells and releasing particles.
This pair of miniature "manipulators" was "carved" by scientists using ultra-fast laser pulses. In the blink of an eye, the laser has "shot" hundreds of billions of times.
Precisely because it is fast enough, it can make the laser "focus on one point" instantly and carve precise and complex manipulators in the micron-level area.
Although this "micromanipulator" is still being polished in the laboratory, it has already allowed us to see new possibilities in medical technology.
In the future, cancer cells can be accurately captured without surgery, and drugs can be delivered targetedly without needles. The once dream of "swallowing nanodoctors to treat diseases" is being turned into a tangible reality step by step by Chinese scientists.
