Abstract

The embodiment of the invention relates to the technical field of semiconductors and provides a digital microfluidic control system and a liquid droplet driving method. The method comprises the following steps: acquiring control parameters of a digital microfluidic control chip and outputting into a microcontroller by a host computer on the basis of a user operation edition electrification sequence, converting the control parameters into a level signal and transmitting to a relay module to open a control end of the relay module by the microcontroller, correspondingly closing a controlled end after the control end of the relay module is opened, enabling a power supply driving module, the controlled end of the relay module and the microfluidic control chip to form an electric circuit, and supplying a driving voltage to the microfluidic control chip to drive liquid droplets to move by the power supply driving module. Movement of the liquid droplets correspond to uniform shaking and mixingoperation on artificially synthesized DNA (Deoxyribonucleic Acid), the uniform shaking times are set up by a user through the digital microfluidic control system, then automatic execution of DNA synthesis can be achieved, and the system is low in labor cost and high in synthesis efficiency.

Description

technical field

[0001] Embodiments of the present invention relate to the technical field of semiconductors, and in particular, to a digital microfluidic system and a droplet driving method. Background technique

[0002] With the development of biology, DNA has developed from information reading to artificial synthesis, and artificial synthetic DNA has been widely used in scientific research, medical testing, medicine, agriculture, industry and other fields. The traditional normal temperature operation technology of DNA synthesis is mainly completed manually, which requires manual shaking and pipetting. In addition, it is also necessary to manually judge whether the reaction is complete under different lights. The labor cost is very high, and the synthesis efficiency is low. Contents of the invention

[0003] The purpose of the embodiments of the present invention is to provide a digital microfluidic system and a liquid droplet driving method to improve the above problems....
