1. An apparatus for separating micro-nano scale particles based on microfluidic chromatography using surface acoustic waves, comprising:

  • a piezoelectric substrate;

    a pair of transducers, which are patterned on the piezoelectric substrate and generate surface acoustic waves when electric energy is applied to the piezoelectric substrate;

    a microfluidic chip, which is mounted on the piezoelectric substrate and include a microfluidic channel disposed between the pair of transducers, wherein a fluid including micro-nano scale particles flows in the microfluidic channel; and

    a detection unit, which detects micro-nano scale particles separated by the surface acoustic waves while the micro-nano scale particles pass through the microfluidic channel,wherein forces of the surface acoustic waves generated by the pair of transducers are formed in a direction opposite to a fluid flow to generate flow resistance to the micro-nano scale particles which flows in the microfluidic channel.
