Description

technical field [0001] The invention relates to the technical field of biological impedance detection, in particular to an impedance biosensor and a biological impedance detection and analysis method. Background technique [0002] Food safety and animal diseases are one of the most prominent problems facing our country. At present, food safety accidents are in a period of frequent occurrence, and highly pathogenic animal diseases also occur from time to time. The screening of pathogenic microorganisms is the key to food safety and animal disease prevention and control. Since the existing routine detection methods are usually unable to achieve on-site rapid detection, there is an urgent need to develop rapid detection technologies for pathogenic microorganisms. [0003] Impedance biosensor is a new type of biological detection technology, which has the advantages of fast detection speed, high sensitivity and simple operation, and has attracted the attention of researchers an...
