Injection of robots into the human body to diagnose and treat diseases

A recent paper published in Science Robotics is the promise for the possibility of being able to open the door to new treatments in the health field. This technology aims to assist in accessing difficult sites in the human body, and aims to revolutionize the way we are diagnosed as well as treated for various diseases and health problems.

Thus, scientists have created microscopic “robots”, more precisely the size of blood cells, which were, at an early stage of animal studies, magnetically guided to various locations in rat stomachs, and they claim to be promising tools for diagnosis and treatment of diseases in difficult-to-reach areas of the body (through methods known and available).

These “robots” are operated remotely and were created from small algae coated with biocompatible magnetic particles, which could be located in tissues relatively close to the surface of the skin, through images of the natural luminescence of the algae, as well as in harder to reach by magnetic resonance imaging. So, says a statement made by the British university of Edinburgh, released this week.

The publication, which does not reveal in detail how the remote control of these microscopic “robots” is carried out, nevertheless states that these devices are sensitive to chemical alterations indicative of a disease, which gives them the potential to become useful such as probes, thus being able to “travel” through the body through biological fluids such as blood or even gastric juice.

For the devices to function and biologically degrade in the body, it can be adapted by adjusting the thickness of the magnetic coating.

The paper was published in the journal Science Robotics and was led by the University of Hong Kong in China in collaboration with the universities of Edinburgh and Manchester, both in the UK.
