Abstract

The invention provides a liquid monitoring method and system. The method comprises the following steps: irradiating a microfluidics device filled with liquid through light with constant strength untilat least one of light sensitive sensors arranged in a plurality of preset detection area of the microfluidics device receives the light transmitting the liquid; acquiring a plurality of photoelectriccurrent output by the plurality of light sensitive sensors while the liquid flows; and monitoring physical parameters of the liquid in real time on the basis of the plurality of photoelectric currentvalues. According to the scheme, the physical parameters of the liquid can be accurately monitored in real time.

Description

technical field [0001] The invention relates to the technical field of microfluidic devices, in particular to a method and system for monitoring liquids. Background technique [0002] A microfluidic system is a device system that controls the movement of tiny droplets to perform experiments such as physical and chemical reactions and biological detection. During experiments such as chemical reactions and biological detection using microfluidic systems, it is necessary to detect the physical and chemical properties of droplets placed in microfluidic devices in real time, for example, including concentration, position, size, shape and temperature information, etc. . Because the measurement of droplets is very small, it is difficult for experimenters to use traditional methods to measure the concentration, position, size, shape and temperature information of droplets in real time. Moreover, during the movement of tiny droplets, physical parameters such as position, size, shap...
