Asthma affects 20 million people living in the U.S. Asthma and cystic fibrosis patients have a thick layer of mucus that forms over the airway epithelium making it hard to deliver medication. We hypothesize that by using magnetic particles with the ability to physically oscillate and rotate, we can deliver drugs by cutting through mucus filaments. We will test this by developing a microscope insert that generates a rotating magnetic field allowing magnetic particles to rotate.
