Blood testing via sound waves may replace some tissue biopsies

new research , Massachusetts Institute of Technology

In a path breaking move, a new research at the Massachusetts Institute of Technology are devising a way to carry out blood biopsies in a non-intrusive way by making use of sound waves. The cells in a human body secrete nanoscale packets called exosomes that carry important messages from one part of the body to another.

The research focuses on intercepting those messages to help diagnose problems ranging from cancer to fetal abnormalities. The same team of researchers have worked together to report the effect of separate cells on their exposure to sound waves back in the year 2014. The existing methods for isolating exosomes require high-speed centrifugation which takes nearly 24 hours to perform.

Based on the latest research, a new device has been created that emits certain sound waves that help isolate the exosomes from blood. When made portable, the technology will be very efficient and time saving in diagnosing a range of conditions. The whole process takes less than 25 minutes to process a 100-microliter undiluted blood sample which is way faster than the traditional centrifugation
