Real-Time Label-Free Acoustic Sensing at High Throughput Rate

Professor Gaurav Bahl from the University of Illinois at Urbana-Champaign has developed a device that performs real-time high sensitivity acoustic sensing of flowing fluid-suspended cells and particles using ultra-high-Q microfluidic opto-mechanical resonators (OMFRs). They aim to achieve throughput rate of 50,000 cells/second.
