Of course, you have to take medicine, but it is hard to say whether the medicine you eat can really affect the lesion. To solve this problem, American researchers have developed a nano-robot that can move in animals and have a self-destructive function, which enables accurate delivery of drugs.
A team from the University of California, San Diego, recently released a press release saying they have developed a robot that is only 20 microns long. In the trial, the researchers succeeded in having the robot deliver some of the nanoparticles to their stomach in a living mouse.
The researchers said that the robot is made of polymer material and the outer layer is galvanized. When it enters the stomach of the animal, zinc reacts with stomach acid to produce hydrogen bubbles, which pushes the robot forward in the stomach. A safer design is that the robot will automatically destroy after the task is completed, without any residue.
This technique is very suitable for the treatment of stomach diseases such as stomach ulcers. Efficient and accurate delivery of drugs not only reduces the amount of medication, reduces side effects, but also accelerates the healing of stomach problems.
But the researchers also pointed out that this technology is still a long way from the real clinical application, but has successfully taken the first step, and its future application prospects will be considerable.
