METHOD FOR REGULATING ARRANGEMENT OF NANOPARTICLES AT THREE-PHASE INTERFACE BASED ON MICROFLUIDIC CHIP

원문 (중국어)

A method for regulating arrangement of nanoparticles at three-phase interface based on microfluidic chip is disclosed. The method comprises following steps: Step S1: preprocessing a microfluidic chip; Step S2: preparing three-phase fluids of water, gas and oil and injecting into fluid inlets of the microfluidic chip by utilizing high-precision injection pumps; Step S3: preparing a nanoparticle solution and injecting into a nanoparticle capture region of the microfluidic chip; Step S4: controlling arrangement and concentration of the nanoparticle solution by adjusting an electric field of the microfluidic chip; Step S5: monitoring stability of the three-phase fluids and behaviors of the nanoparticle solution at the three-phase interface in real time by utilizing a microscope and sensors; Step S6: analyzing and evaluating the data of the behaviors collected in the Step S5; and Step S7: cleaning the microfluidic chip.
