Microfluidic device. a] device comprising of a squared cross-section glass capillary (length: 50 mm, internal width: 300 μ m and wall thickness: 150 μ m), coupled to a PZT transducer (length: 40 mm, width: 9 mm and thickness: 1 mm) and mounted on a glass platform. b] Modulus of impedance (Ω) for the air-filled and the liquid-filled micro-capillary, respectively. Frequency range: 2.13-2.40 MHz.
