This application discloses a method for detecting CHI3L1 protein based on microfluidic fiber optic sensing, belonging to the field of biomedical detection technology. The method includes: providing a microstructured fiber optic sensing unit with a through-flow microfluidic channel; immobilizing a CHI3L1 protein-specific antibody on the inner surface of the microfluidic channel; injecting the sample to be tested into the channel, causing the CHI3L1 protein to be specifically captured; and achieving quantitative detection of the CHI3L1 protein by detecting the drift of fiber optic transmission spectral characteristic parameters caused by antigen-antibody binding. This invention combines microfluidics with fiber optic sensing, utilizing antibody immobilization on the inner wall of the microfluidic channel to increase the interaction efficiency between the light field and biomolecules, significantly improving detection sensitivity. It has the advantages of rapid detection, low sample consumption, and label-free operation, making it suitable for early non-invasive screening and dynamic monitoring of clinical liver fibrosis.

This application provides a machine vision-based system and method for monitoring the component content of inert materials, relating to the field of inert material identification technology. The system includes: a trough-shaped belt conveyor for transporting inert materials with the component content to be monitored; an inert material spreading module disposed within the belt trough formed by the trough-shaped belt conveyor, used to spread the inert material within the belt trough; and a machine vision module disposed above the inert material spreading module for acquiring images of the spread inert material to detect its component content. This application's embodiment can detect the component content of the material in real time during the inert material transport process, effectively overcoming the shortcomings of weak representativeness in manual sampling, and can quickly obtain detection results, resulting in high speed, high efficiency, and significantly improved construction efficiency.

The invention relates to an automatic detection and display algorithm based on a periodontal detector, which is applied to a P.g bacterium automatic detection device, and the device comprises a main controller, a cover state detection module, a test tube existence detection module, a detection execution module, a nixie tube display module, a power supply module and a power supply key integrated with a multicolor state indicating lamp. The algorithm is executed according to the following steps: S1, power-on self-test and state indication: after a power line is connected, a user presses down a power key, and a main controller is powered on and starts a self-test program; during the self-checking period, the main controller controls the multi-color state indicating lamp to be lightened in a red flashing mode; the technical problems that in a detection scene for P.g bacteria and other specific strains in the prior art, a detection method and existing simple automatic equipment both depend on manual judgment in operation, are insufficient in safety and reliability, lack in equipment state indication, poor in man-machine interaction experience, opaque in detection process and high in result interpretation threshold are solved.
