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.
The method combines a low-frequency ultrasonic wave to levitate the cells and confine them to a single layer within a fluid and a high-frequency ultrasonic wave to measure the cell’s stiffness. “An acoustic wave is a pressure wave so it travels as a wave of high and low pressure...
