Abstract

The invention provides a sensor chip for detecting microcystic toxins and mobile monitoring equipment thereof. The sensor chip comprises a combined chip body, the upper surface of the combined chip body is modified with a microcystic toxin molecularly-imprinted membrane, and the microcystic toxin molecularly-imprinted membrane is provided with micropores for specific recognition of microcystic toxins. The mobile monitoring equipment comprises an optical system with the sensor chip, and a flow path system. The invention further provides a device for detecting the content of microcystic toxins in a water area in real time. The content of microcystic toxins in the water area can be detected in real time in situ, and the instrument can operate automatically in the field without artificial participation.

Description

technical field [0001] The invention relates to the technical field of microcystin detection, in particular to a sensor chip for microcystin detection and a mobile monitoring device thereof. Background technique [0002] Microcystins are a class of hepatotoxins released by harmful cyanobacterial blooms with strong cancer-promoting effects. They are monocyclic heptapeptide organic compounds that are found in water sources all over the world. Due to the eutrophication of lakes and reservoirs, water bodies polluted by microcystins continue to grow, posing a huge threat to human health. Among the various algal toxins that have been discovered, microcystin is currently known to be the algal toxin with the highest frequency, the largest amount of production and the most serious damage in cyanobacterial bloom pollution. Due to the high stability of algal toxins, the conventional water treatment process cannot remove algal toxins very effectively, so the detection of microcystins i...
