Swarms of tiny nose robots could clear infected sinuses, researchers say | Medical research

The researchers claimed that small robots, each of which is not larger than a spot of dust, can be spread to treat stubborn sinuses before they are detonated across the nose into a tissue.

Microscopic strings are a small part of the width of human hair and it was successfully included in the animal sinuses in the previous clinical trials by researchers at universities in China and Hong Kong.

Sands are injected into the sinus cavity through a tied canal through the nose and directed to their goal by electromagnetism, where they can be made to heat and stimulate chemical reactions to wipe bacterial infections. There is hope that the technology will eventually be accurately reducing the dependence on antibiotics and other generalized drugs.

Small devices are part of the field of expansion of small tendons and nanoparticles for use in medicine. It was also developed to connect medicines and remove bacteria from medical transplants such as supports and hernia.

Experts believe that they can be in the clinical use of the treatment of infections in the bombs, intestines and sinuses within five to 10 years. Scholars ChinaSwitzerland, the United States and the United Kingdom are developing more sophisticated versions capable of moving across the bloodstream.

The latest development came from cooperation with academics at the Chinese University of Hong Kong, and universities in Guangchchi, Hentna, Jiangsu, Yangzhou and Macao.

Researchers in the emerging field include that the risks include some small small tendons that are left behind after treatment and that may cause long -term side effects.

There is another possible problem, which technology experts were martyred, which is the general doubts about the idea of ​​welcoming robots in theories of the human body and the conspiracy arising about fears that robots can be activated without approval.

The latest penetration, based on animal experiments instead of human experiments, includes “narcotic” magnetic molecules with copper atoms that doctors include with catheter before directing their goal under a magnetic field.

Slavings can be heated by responding to light from the optical fibers that are also inserted into the body as part of the treatment. This allows the small tendons to relieve and penetrate the sticky pus that is a barrier in front of the infection site. The light source also calls for microscopic tendons to disrupt the walls of bacterial cells and release interactive oxygen types that kill bacteria.

the study , Published In science robots, it showed that the robots were able to eliminate bacteria from the sinuses of pigs and could get rid of infections in living rabbits with “lack of clear damage to tissues.”

The researchers produced a model of how technology works on a person, as robot swarms are deployed in practical theater conditions, allowing doctors to see their progress using X -rays. Future applications can include bacterial infections in the respiratory system, stomach, intestine, bladder and analysis.

They said: “We have the proposed micro -platform we have the advantages of non -gas, minimum resistance, and drug -free intervention.”

Professor Silvan Martel, director of Nano Robotat Laboratory in Polytechnique de Montréal in Canada, who did not participate in the research, said the science seems effective.

“It is like a missile that you can direct with a magnetic field,” he said.

He expected the small tendons available for treatments within three to five years, but perhaps not for another decade, as the organizers still need to agree to their use and manufacturing operations, which differ from standard drugs.

“The main feature with small boats is targeting,” said Martel. “Instead of taking the medicine that goes to the bloodstream and a small amount that goes to the right site, you can target.”

He said that the audience will set any concerns about the idea of ​​automatic devices in their bodies.

“Maybe at first [they will be afraid]He said, “But they will attack it very quickly.”

“The audience may be suspicious of non -biological things such as the inclusion of nanoparticles in our bodies. Even conspiracy theories may even lead to conspiracy theories.

“But it is important to look at what is designed for nano -nano. In this case, we see an example of a targeted intervention to reduce or eliminate an infection in a local currency.

“NANO-Robots behavior is often simpler and more targeted than many medications and can effectively complete a wide range of treatments.”
