Abstract

The invention discloses a capillary bioanalysis system, and an analytical method and applications thereof, and belongs to the field of medical equipment and biological detection technologies. The capillary bioanalysis system comprises a three-dimensional movement sample injecting platform, a temperature control-optical detection module, a magnetic field control module, a fluid control unit and a capillary array. The three-dimensional movement sample injecting platform and the fluid control unit are arranged on the two sides of the capillary array, and the capillary array is provided with the temperature control-optical detection module and the magnetic field control module. According to the capillary bioanalysis system, the droplet technology and the magnetic bead technology are combined, and bioanalysis processes such as loop-mediated isothermal amplification, fluorescence quantitative PCR analysis and immunochemiluminometry are integrated in capillaries. Advantages of the capillary bioanalysis system are that: volume is small, analysis speed is fast, detecting flux is large, and automation degree of operation is high. The capillary bioanalysis system is flexible in application, is suitable for analysis of single sample, batches of samples and on-site rapid detection, is capable of reducing acquisition cost and operation cost of equipment significantly, and possesses excellent economic benefits.

Description

technical field [0001] The invention belongs to the technical field of medical equipment and biological detection, and in particular relates to a capillary biological analysis system and its analysis method and application. Background technique [0002] The capillary analysis system has many advantages: (1) The capillary occupies a small area, which is convenient for parallel analysis; (2) Standard capillaries with different materials and series specifications are available, and the price is low; (3) The consumption of reagents and samples is small; (4) Fluid control is simple. Therefore, capillary tubes are widely used in various types of biological analysis, such as: nucleic acid extraction, nucleic acid amplification, electrophoretic separation, and flow cytometry analysis. [0003] The capillary analysis system also has some deficiencies, the most prominent of which is that it is difficult to realize complex analysis functions due to its simple structure. Therefore, ca...
