Blood Testing Via Sound Waves May Replace Some Tissue Biopsies
“Cells secrete nanoscale packets called exosomes that carry important messages from one part of the body to another. Scientists from MIT and other institutions have now devised a way to intercept these messages, which could be used to diagnose problems such as cancer or fetal abnormalities.
Their new device uses a combination of microfluidics and sound waves to isolate these exosomes from blood. The researchers hope to incorporate this technology into a portable device that could analyze patient blood samples for rapid diagnosis, without involving the cumbersome and time-consuming ultracentrifugation method commonly used today…”
