DEVICE AND METHOD FOR SEPARATING MICROPARTICLES USING SURFACE ACOUSTIC WAVE-BASED MICROFLUIDIC CHROMATOGRAPHY

摘要

The present invention relates to a device and a method for separating microparticles using surface acoustic wave-based microfluidic chromatography. The device includes: a piezoelectric substrate; a pair of transducers generating surface acoustic waves by applying electric energy to the piezoelectric substrate by being patterned on the piezoelectric substrate; a microfluidic chip including a microfluidic channel for flowing fluid containing microparticles in between the transducers, and installed on the piezoelectric substrate; and a detection unit for detecting the microparticles separated by the surface acoustic wave while passing through the microfluidic channel. According to the present invention, a user can generate flow resistivity on the flowing microparticles and vary the movement speed per size of the microparticles for separeating the microparticles in the detection unit, and detect the kind and size of materials using the detection unit.;COPYRIGHT KIPO 2014
