Scientists at City University in Hong Kong have uncovered a magnetic “spray” that is capable of transforming things into moving robots, which can be used to move between drugs throughout the body. Scientists showcased their innovation made from polyvinyl alcohol, gluten and iron particles, and launched it “M- Noun spray” It is able to adhere to the target body and when activated, it allows the body to walk, roll and crawl using a magnetic field.
According to the British “Daily Mail” website, the team expects that their innovations will be applied to pills, which doctors transfer to a targeted part of the body. Dr. Chen Yajing, who led the research team, told New Atlas Our idea is that by wearing this magnetosphere, we can transform any objects into a robot and control its movement, and all the raw materials for M-spray , Precisely PVA The gluten and iron particles are biocompatible, and the chipped layer can be absorbed or secreted by the human body. “
The spray can also be removed from the body using an oscillating magnetic field to split it into a powder – all while leaving the body intact, and Yajing also emphasized that the powder is pushed by the body afterward, and the motion mode can also be reprogrammed on demand by wetting the hardened paint and turning it into a glue-like substance..
Then, by applying a strong magnetic field, the magnetic particles inside the jacket can be redistributed and realigned, changing the way the robot interacts with the magnetic field.
In the experiments, the team sprayed capsules and gave them to anesthetized rabbits, and the pills were tracked through the rabbit’s body using radiography, and the researchers observed that the coating melted when the capsule reached the target site.
“We hope this construction strategy will contribute to the development and application of Milli robots in various fields, such as active transport, moving sensors and devices, especially for tasks in a limited space,” said Yajing“.
The team believes the capabilities demonstrate a number of biomedical applications, including catheterization and drug delivery.
