Abstract

The embodiment of the invention provides a temperature control system, a detection system and a temperature control method of a micro-fluidic chip. The temperature control system comprises a circuit structure which is used for being arranged in the functional layer in the micro-fluidic chip and corresponding to the reaction area of the micro-fluidic chip, wherein the circuit structure comprises atleast two thermistors and a plurality of ports and the ports comprises an input end and an output end; and a main control unit which is electrically connected with each port and is used for selectingdifferent input ends and / or different output ends to form use circuits with different resistance values so that the circuit structure can be switched between being used as a heating device and beingused as a temperature sensor. The two multiplexing functions of the circuit structure do not interfere with each other, the temperature of the reaction area can be controlled in real time, it is guaranteed that the reaction area is always at the needed temperature without additionally increasing the size of the temperature control system or the size of the detection system and the cost is low.

Description

technical field [0001] The present application relates to the field of microfluidic technology, in particular, the present application relates to a temperature control system, a detection system and a temperature control method of a microfluidic chip. Background technique [0002] Microfluidics is a technology for precise control and manipulation of microscale fluids, which provides simple device structure and packaging, smaller volume, and the ability to process smaller amounts of reagents in parallel. Its driving methods are diverse, including mechanical, electrical, magnetic, thermal, optical and so on. Dielectric wetting EWOD is one of the most applicable methods due to its low power consumption and simple device fabrication. Digital microfluidics based on dielectric wetting EWOD integrates operations including droplet generation, transportation, and merging into a micron-scale chip, and can manipulate multiple droplets at the same time. It has a more flexible control m...
