  • Methods and devices for acoustophoretic operations in polymer chips
    Patent number: 11331668
    Abstract: The invention relates to a method of performing an acoustophoretic operation, comprising the steps of: a. providing an acoustophoretic chip comprising a polymer substrate in which a microfluidic flow channel is positioned, b. providing at least one ultrasound transducer in acoustic contact with one surface of the substrate, c. actuating the at least one ultrasound transducer at a frequency f that corresponds to an acoustic resonance peak of the substrate including the microfluidic flow channel filled with a liquid suspension, and d. providing the liquid suspension in the flow channel to perform the acoustophoretic operation on the liquid suspension. The invention further relates to an acoustophoretic device, a method of producing an acoustophoretic device, and a microfluidic system comprising the acoustophoretic device.
