Abstract

The invention discloses an RCA (rolling circle amplification)-terahertz metamaterial biosensor for parallel detection of multiple pathogenic bacteria, and a detection method of the biosensor. The biosensor comprises a terahertz metamaterial, capturing probes used for recognizing different pathogenic bacteria and coated with reaction zones made of the terahertz metamaterial, and a polystyrene slide; the upper layer of the terahertz metamaterial is covered with the polystyrene slide and forms a liquid film cavity used for liquid phase amplified reaction; the coated capturing probes of the RCA-terahertz metamaterial biosensor are hybridized with RCA annular templates to realize in-situ replication amplification. A stable and reliable result can be obtained with the method, and the parallel detection of six clinical common pathogenic bacteria can be performed within 3 hours.

Description

technical field [0001] The invention belongs to the detection field, and in particular relates to a rolling circle amplification-terahertz metamaterial biosensor for parallel detection of various pathogenic bacteria, and also relates to a method for parallel detection of various pathogenic bacteria by using the biosensor. Background technique [0002] Rapid and accurate detection of the species of pathogenic bacteria is crucial for the diagnosis and follow-up treatment of clinical infectious diseases. At present, in clinical microbiology, diagnostic methods based on the enzymatic and biochemical reaction characteristics of bacteria after culture are still widely used. Although this classic method is accurate, it often takes a long time, usually after the bacteria are isolated and cultured. It takes 7 days to conduct complex biochemical reaction experiments to accurately obtain the type of pathogenic bacteria. Although the matrix-assisted laser desorption ionization-time-of-...
