According to the report of the New Scientist of the United States, recently scientists have been inspired by fish swimming and developed a new "nano-fish robot" that can be used to deliver drugs in the human body.
The nanofish is very small and 100 times smaller than a grain of sand. The "nano-fish" is magnetically driven and contains tiny gold and nickel components with a silver hinge as the connection. Its speed and direction are determined by the direction and strength of the magnetic field.
The robot was developed by researchers at the University of California, San Diego, and they hope their invention can be applied to the medical field, such as the transfer of analgesic drugs to specific parts of the body.
Although other teams have also developed "nano-swimming robots" with similar functions, most of them look more like a small submarine. How to move nano-bots forward is traditionally inspired by the spiral tail of bacteria. Experiments have found that this "nano-fish" is more effective than previous similar-function robots.
