Abstract

The invention belongs to the technical field of medical biological detection, and discloses an automatic detection device and an automatic detection method for pathogens. The automatic detection device provided by the present invention includes a control system, a first robotic arm, a second robotic arm, a biosensor and an optical fiber spectrometer, wherein: the biosensor is arranged on the second robotic arm; under the control of the control system , the first robotic arm adds the liquid sample to the surface of the biosensor and cleans the surface of the sensor; the second robotic arm aligns the surface of the biosensor with the optical fiber probe of the optical fiber spectrometer for optical detection; the optical fiber spectrometer detects and collects the optical reflection of the biosensor spectral data. The automatic detection device and detection method of the present invention not only improve the detection throughput, but also avoid risks such as mistakes and cross-infection caused by personnel detection operations, and because the optical biosensor based on nano-material-porous silicon is used, it has higher performance. detection sensitivity.

Description

technical field [0001] The invention belongs to the technical field of biological detection, in particular to a pathogen detection device and detection method. Background technique [0002] Novel Coronavirus Disease 2019 (COVID-19), referred to as "New Coronary Pneumonia", refers to the pneumonia caused by the 2019 Novel Coronavirus infection, which is an acute respiratory infection. The World Health Organization (WHO) named it "COVID-19" on February 11, 2020. On the same day, the coronavirus research group of the International Committee on Taxonomy of Viruses named the new coronavirus "SARS-CoV-2" according to the naming rules of taxonomy. [0003] At present, the detection of the new coronavirus SARS-CoV-2 is mainly limited to hospitals and CDCs, and the mainstream technology is polymerase chain reaction based on nucleic acid amplification detection. However, nucleic acid extraction and amplification is a complex process, and the accuracy of the results will be affected ...
