Microrobots have been created and used to treat the most common form of pneumonia that infects patients in ICU. In experiments, currently carried out in mice at the University of California San Diego, the tiny robots swam around the lungs and delivered antibiotics that killed the disease-causing bacteria. The amount of antibiotics needed is a tiny fraction of the amount currently used to treat this infection intravenously. The robots are made from algae cells (this allows them to move) covered in antibiotic-filled nanoparticles. These nanoparticles are made with tiny spheres that are coated with the cell membranes of neutrophils – a...
