Abstract: The present invention provides an apparatus and method for washing and concentrating microparticles encapsulated in microscale droplets using an acoustic radiation force. The apparatus includes: a piezoelectric substrate; a slanted finger interdigital transducer (SIDT) electrode deposited on the piezoelectric substrate and configured to generate surface acoustic waves under an AC signal applied thereto; and a microfluidic chip which is adhered to the piezoelectric substrate with being spaced apart from the SIDT electrode, has a microscale channel section formed therein, in which a single continuous phase and a plurality of dispersed phases are injected, respectively, and includes a plurality of inlet ports into which continuous and dispersed phases are injected, and a discharge port from which a plurality of droplets composed of the continuous and dispersed phases and generated by the intersection thereof are discharged.

Abstract: The present invention relates to a method for coating a quantum dot using droplet evaporation in a confined system, and may provide a new method capable of easily coating the quantum dots by maximizing the continuous Marangoni effect which occurs through the multi-component droplet evaporation phenomenon in the confined system without separate chemical-physical treatment.
