A microfluidic ultrasonic manipulation system is used for controlled selection, re-tention and optical characterization of individual particles or cells. The system is based on a chip-integrated focused ultrasonic resonator that is actuated on either one or both of two different frequencies. Particles are pre-aligned, and either bypassed through or injected and retained in the focused resonator, depending on the actuation mode. Dynamic flow cytometry is demonstrated by real-time optical monitoring of controlled numbers of retained and positioned cells or beads.
