APPARATUS AND METHOD FOR WASHING AND ENRICHMENT OF MICROPARTICLES ENCAPSULATED IN MICROSCALE DROPLETS USING ACOUSTIC RADIATION FORCE

摘要

The present invention relates to an apparatus and method for cleaning and concentrating particles in a micro-scale droplet using acoustic radiation force, specifically, it is possible to selectively clean particles in a micro-scale droplet when desired in a continuous, non-contact and non-marking manner, It relates to an apparatus and method for cleaning and concentrating particles in a micro-scale droplet using an acoustic radiation force capable of increasing the population by concentrating the particles in the droplet. An apparatus for cleaning and concentrating particles in a micro-scale droplet using acoustic radiation force according to the present invention includes: a piezoelectric substrate; An SIDT electrode deposited on the piezoelectric substrate and receiving an AC signal to generate surface acoustic waves; And a block shape, which is spaced apart from the SIDT electrode and adhered to the piezoelectric substrate, and a single continuous phase and a plurality of dispersed phases are injected therein to form a plurality of different droplets and flow through a micro-scale channel. A microfluidic chip which is formed, and has a plurality of inlets for respectively injecting the single continuous phase and a plurality of dispersed phases, and outlets for discharging a plurality of droplets that are formed at intersections, respectively; Includes.
