Nanoengineers at the University of California, San Diego, have developed anti-pneumonia mini-robots that can swim around the lungs, deliver drugs and use them to clear life-threatening bacterial pneumonia infections
.
The miniature robots are made of algae cells with surfaces embellished with antibiotic-filled nanoparticles
.
The team used miniature robots to treat mice with acute and potentially fatal pneumonia caused by Pseudomonas aeruginosa
.
Treatment with microrobots is more effective
than intravenous antibiotics.
The team's approach is very effective because it transports the drug where it is needed, rather than spreading it to other parts of
the body.

With intravenous injections, sometimes only a small fraction of the antibiotics enter the lungs
