They created mini robots to treat brain diseases such as Parkinson’s

They developed micro robots from 100 nanometers to just a few millimeters prepared to treat different diseases of the central nervous system such as Parkinson’s or brain tumors, such as gliomas.

These nanorobots, created by the startup Bionaut Labs, are designed to be injected into the patient’s body and go to the affected area, with the aim of carrying the medicine to treat the condition. They could also be used to perform microsurgery.

The main benefit is that they go to places that are difficult to access in the body, and they carry the right dose, with the potential to reduce side effects. that the administration of these drugs can have in more traditional ways, according to their creators. At the same time, They could be used to carry out interventions in areas of the brain where precision is key to avoiding damage.

For now, tests have already been carried out on sheep and pigs.yes It is estimated that the first tests in humans will be carried out in two years. If approved, the robots could offer key advances over existing treatments for brain diseases and other conditions as well.

These therapeutic micro robots can be designed to measure, with different characteristics and dimensions, depending on the objective of the treatment. Devices contain moving parts that are managed remotely with a compact magnetic controllerwhich allows them to move, cut tissue and deliver the medication to the right place.

The company uses magnetic energy to propel robotsinstead of optical or ultrasound techniques. Magnetic coils located outside the patient’s skull are connected to a computer that can remotely maneuver the tiny robot to the affected part of the brain, before removing it via the same route.

The entire device is easily transportable, unlike an MRI (magnetic resonance imaging), and uses between 10 and 100 times less electricity, according to an AFP note.

“The idea of ​​a micro robot came up long before I was born,” said co-founder and CEO Michael Shpigelmacher, in dialogue with that medium. “One of the most famous examples is an Isaac Asimov book and movie called ‘Fantastic Voyage,’ where a group of scientists go into the brain in a miniaturized spaceship to treat a blood clot.”

In a simulation carried out to show the technology of this system, the robot was seen to slowly follow a pre-programmed path through a container filled with gel, which simulated the density of the human brain.

The robot, a metallic cylinder a few millimeters long, was seen approaching a bag filled with a blue liquid, which was then pierced by the pointed end of the device so that the liquid would flow out.

In this way it was proved how the robot could be used to puncture fluid-filled cysts inside the brain when clinical trials begin in two years.

If successful, the process can be used to treat Dandy-Walker syndrome, a rare brain malformation that affects children as anticipated by its creators.. Sufferers can experience golf ball-sized cysts, which swell and increase pressure in the brain, unleashing a host of dangerous neurological conditions.

The US Food and Drug Administration (FDA) granted Bionaut Labs approvals last year that pave the way for clinical trials to treat the aforementioned syndrome, as well as malignant gliomas.

In the latter case, the tiny robots will be used to inject anticancer drugs directly into brain tumors in a kind of surgical coup.
