Abstract

The invention relates to a preparation method for a microfluidic array controller, and belongs to the technical field of microfluidic control. The preparation method solves the problem that large-scale microfluidic array control is not easy to realize in the prior art. The preparation method comprises the following steps that microfluidic control units are prepared, wherein each microfluidic control unit comprises a microfluidic channel device, a thin-film transistor device and a capacitor; a power supply 1 and a power supply 2 are selected according to the preset requirement; and M*N microfluidic control units are arranged into a M*N array and are connected in a line connection mode. According to the preparation method, the prepared M*N array only needs M+N+2 leads, and the microfluidic control voltage only needs to be about 20 V. The preparation method for the microfluidic array controller has the advantages that the large-scale microfluidic arrays control can be realized, the large-scale microfluidic array control difficulty can be greatly lowered, the number of the leads can be decreased, and a novel technological approach is provided for the practicability of a microfluidic control chip.

Description

technical field

[0001] The invention relates to the technical field of microfluidic control, in particular to a preparation method of a microfluidic array controller. Background technique

[0002] Microfluidic control is a control technology that uses voltage signals to control the movement, segmentation, and fusion of pigment droplets. It is one of the core technologies for realizing micro-electrochemical, chemical, medical and biochips.

[0003] Microfluidic controllers prepared by existing methods generally use arrayed control electrodes to achieve microfluidic control. However, the existing microfluidic controllers are limited by the number of interconnection leads, and the scale of the electrode array is far from meeting the requirements of use, which seriously hinders the popularization and application of microfluidic control chips.

[0004] The structure of the microfluidic array controller prepared by the existing method is as follows: figure 1 As shown, if the siz...
