Acoustic levitation for medicine

    Newer Older

    These drops of solution remain suspended for a long period of time, thanks to the vibrational force of sound waves that keep them stationary in an air column.

    Scientists at Argonne National Laboratory have discovered a way to use sound waves to levitate individual droplets of solutions containing different pharmaceuticals. While the connection between levitation and drug development may not be immediately apparent, a special relationship emerges at the molecular level. Read more »
