Method and system for monitoring a liquid

Abstract

The present invention provides a method and system for monitoring liquid, the method comprising: irradiating light of constant intensity on a microfluidic device placed with liquid so that a plurality of predetermined detection areas of the microfluidic device are set At least one photosensitive sensor in the photosensitive sensor receives the light passing through the liquid; in the process of moving the liquid, a plurality of photocurrent values ​​output by a plurality of photosensitive sensors are obtained in real time; according to the plurality of photocurrent values The physical parameters of the liquid are monitored in real time. The scheme of the invention can monitor the physical parameters of the liquid more accurately and 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...
