Example Embodiment
[0034] The invention provides a digital microfluidic chip based on large and small droplet manipulation based on the current on-medium electrowetting digital microfluidic chip structure and driving method. It should be noted that this embodiment is provided for illustrative purposes, and is not intended to limit the scope of the present invention in any way.
[0035] The cross-sectional schematic diagram of two 90-degree chips of a digital microfluidic chip based on large and small droplet manipulation according to the present invention is as follows: figure 1 , figure 2 As shown, on the first insulating substrate 100 are first electrode layers E1-E10. It should be noted that the material used as the substrate is not fixed, as long as it is insulated, such as quartz, glass, insulating silicon wafer, etc.; and the electrode can be composed of any conductive material, the size and spacing of the electrode, and the specific electrode size. The number is not limited, this manual onl...
