University of California San Diego has developed microscopic robots that can swim around in the lungs, deliver medication and be used to clear up life-threatening cases of bacterial pneumonia. The microrobots are made of algae cells whose surfaces are speckled with antibiotic-filled nanoparticles. The algae provide movement, which allows the microobots to swim around and deliver antibiotics directly to more bacteria in lungs. All mice treated with the robots survived past 30 days, while untreated mice died within three days.Read Long Article
