Deadly pneumonia was cured with the help of microrobots.

Researchers at the University of California, San Diego have developed micro-robots that can swim in their lungs. The devices destroyed pneumonia-causing bacteria in the lungs of mice. As a result of treatment, 100% of mice survived, while in the control group, all individuals died. Microrobots are made from algae cells, the surface of which is speckled with nanoparticles filled with antibiotics. The algae provides propulsion, which allows the microrobots to float and deliver antibiotics directly to more bacteria in the lungs.
