Abstract: Microfluidic chips, microfluidic processing systems, and microfluidic processing methods are provided. A microfluidic chip includes a top plate and a microelectrode dot array arranged under the top plate. The microelectrode dot array includes microelectrode devices connected in a series. Each microelectrode device includes a microfluidic electrode under the top plate, a multi-functional electrode under the microfluidic electrode, and a control circuit under the multi-functional electrode. Each control circuit includes a first storage circuit, a second storage circuit, a microfluidic control and location-sensing circuit, and a temperature and magnetic control circuit. Each first storage circuit reads in a sample operation configuration. Each second storage circuit reads in a magnetic field control configuration. Each microfluidic control and location-sensing circuit enters a sample control status corresponding to a sample operation configuration.
