A device about the size of a dime can manipulate living materials such as blood cells and entire small organisms using sound waves, according to a team of bioengineers and biochemists from Penn State. The device, called acoustic tweezers, is the first technology capable of touchlessly trapping and manipulating Caenorhabditis elegans (C. elegans), a one millimeter-long roundworm that is an important model system for studying diseases and development in humans. Acoustic tweezers are also capable of precisely manipulating cellular-scale objects that are essential to many areas of fundamental biomedical research.
