Caption

This new biomedical device manipulates particles as small as DNA (2.5 nanometers) with sound-induced electric fields. Four transducers send sound waves into a substrate that creates electricity as it vibrates, producing patterns of electric-acoustic waves that control particles in the liquid-filled chamber above.
