Technical Field

[0001] The utility model relates to the field of bipolar microfluidics, in particular to a bipolar microfluidics production device. Background Art

[0002] Bipolar microfluidics is a technology that uses bipolar electrodes to achieve fluid manipulation in microfluidic chips. Bipolar microfluidic chips achieve precise manipulation of tiny particles and cells through the synergistic effects of electric fields, electroosmotic flow, and dielectrophoretic forces.

[0003] However, when processing fluids, current bipolar microfluidic devices have difficulty accurately controlling the fluid temperature during transmission, which will lead to reduced sample activity and reaction efficiency. In addition, after the fluid is processed, the protection measures for sample activity and chemical stability are poor, thus affecting the accuracy and reliability of the processing results. Therefore, we propose a bipolar microfluidic production device to solve the above problems. Utility Model Content
