Sound Waves Levitate Cells To Detect Stiffness Changes That Could Signal Disease
Physicists are literally applying rocket science to the field of medical diagnostics. With a few key changes, the researchers used a noninvasive ultrasonic technique originally developed to detect microscopic flaws in solid fuel rockets to successfully detect cell stiffness changes associated with certain cancers and other diseases. The method uses sound waves to manipulate and probe cells. ... Read News
