The detection is based on the optical signal change generated by the interaction between microorganisms and light. Among them, the fluorescent microorganism sensor is a more common one. Certain fluorescent markers can specifically bind to microorganisms, and when excited by light of a certain wavelength, the fluorescent markers will emit a fluorescent signal, the intensity of which is proportional to the number of microorganisms. By detecting the intensity of the fluorescent signal, the concentration of microorganisms in water can be determined. In addition, there are optical microorganism sensors 4 based on surface plasmon resonance (SPR) technology. After the microorganisms combine with the recognition molecules on the surface of the sensor, the refractive index of the sensor surface will change, which will cause the change of the SPR signal, and the detection of microorganisms is realized by monitoring the change of the SPR signal.
