Experimenting with a robot with a slime-like appearance

The mucus can be manipulated with a magnetic field, which helps it navigate through tight spaces and is especially ideal for picking up small objects inside the human body.

Researchers in Hong Kong have recently released a new robot with a slime-like shape that can be used to pick up anything from inside the human body - something that medicine still does today. quite limited.

According to Professor Li Zhang, who led the study, he and his colleagues succeeded in mixing neodymium magnet particles with solder, a common household cleaner, and polyvinyl resin to form a slime that can be controllable.

Specifically, this slime can move around, driven by magnets, forming a C-shaped hook, or an O-shaped circle, allowing it to "grab" desired objects. out of places where conventional methods are difficult to reach.

Not only that, it can also easily change the shape of matter, turning from a solid block to a liquid, from there crept into the narrow crevices in the body to do "mission".

This mucus is expected to make a breakthrough in medicine.

The robot is currently still in the basic research stage, the researchers say. However, their goal is to be able to bring the robot to use inside the human body, or specifically inside the digestive tract. Most importantly, it is the ability to retrieve non-food objects that are accidentally swallowed by humans.

However, there is a danger that the magnetic particles in the slime can be toxic to the body. To solve this problem, Zhang and his team coated the slime with a layer of silica. They believe this will create a protective layer that can prevent harmful particles from interacting with the human body.

However, the effectiveness of the robot is still something to be considered carefully before practical application.
