The joint development of technology and medicine has allowed us to see some treatment methods that were unimaginable until now. On the other hand, the scientific world will now be able to move inside our bodies, in our veins and narrow channels, to open blockages, stop drugs and perform micro-surgeries. robots focused on development.

One of these robots has recently broken new ground. Scientists work with robots made of algae cells and covered with a layer of antibiotic nanoparticles. managed to clear the inflammation in the lungs of mice. In the future, the robot wants to clear up deadly bacterial infections in humans.

How do robots achieve this?

• Green: algae, brown: nanoparticles

The robot used was actually not a single robot. The structure that relieved the pneumonia was actually a swarm of many microscopic swimming robots injected into the body. Every robot in the swarm from algae cells is produced so that it can move through the lungs.

Nanoparticles placed on algae cells are covered with membranes of neutrophils, a type of white blood cell. from small polymer spheres is formed. These membranes neutralize ‘inflammatory molecules’ produced by bacteria and the body’s own immune system. In this way, both nanoparticles and algae are broken down naturally. In other words, the robot that enters the body does not come out again, through your body again. naturally destroyed.

So how effective is the use of robots?

Thanks to robots, scientists can give patients the necessary treatment in microscopic format can perform. In addition, if vaccines were used in this test instead of robots, loaded on algae up to 3000 times the dose of antibiotics would be necessary. So the difference is huge.

Scientists will use microbots in their next research. how it interacts with the immune system will review. It will then prepare the robots for testing in larger animals and eventually humans.
