Tiny swimming robots treat deadly pneumonia in mice

UC San Diego engineers have developed microscopic robots, called microrobots, that can swim around in the lungs, deliver medication and be used to clear up life-threatening cases of bacterial pneumonia. In mice, the microrobots safely eliminated pneumonia-causing bacteria in the lungs and resulted in 100% survival. By contrast, untreated mice all died within three days after infection.

UTEP Researchers Develop Nanohybrid Vehicle to Optimally Deliver Drugs Into the Human Body

The researchers discovered that encapsulating ellagic acid in chitosan, a sugar, reduces its inherent cytotoxicity while enhancing its anti-oxidant properties. The chitosan shell, which makes up the hard outer skeleton of shellfish, also permits EA delivery via a rapid burst phase and a relatively slow phase.
