Abstract
Systems and methods for cleansing blood are disclosed herein. The methods include acoustically separating target particles from elements of whole blood. The whole blood and capture particles are flowed through a microfluidic separation channel formed in a thermoplastic. At least one bulk acoustic transducer is attached to the microfluidic separation channel. A standing acoustic wave, imparted on the channel and its contents by the bulk acoustic transducer, drives the formed elements of the blood and target particles to specific aggregation axes.
