Abstract

The invention provides an immunodetection and biochemical detection-based micro-fluidic chip, a detector and a detection method, wherein the micro-fluidic chip comprises a substrate, wherein a samplefeeding unit, an immunodetection region and a biochemical detection region are arranged on the substrate; the immunodetection region comprises a first reaction unit and a waste liquid recovery unit; afirst curing agent layer is fixed in the first reaction unit; the biochemical detection region comprises a second reaction unit, and a second curing agent layer is fixed in the second reaction unit;the sample feeding unit is communicated with the first reaction unit and the second reaction unit through a micro-channel separately. The detector integrates two different types of detection on the chip, the structure is simple, the flow of the fluid can be accurately controlled, and the detection is fast and accurate.

Description

technical field [0001] The invention belongs to the technical field of detection equipment and methods, and relates to a microfluidic chip, a detector and a detection method based on immune detection and biochemical detection. Background technique [0002] The judgment of disease needs to combine different information combinations, such as biochemical detection, immune detection and imaging detection. At present, most of the detection equipment is oriented to a certain type of detection, such as biochemical analyzers and immune analyzers, all of which use a certain type of substance as the detection substance. In addition, the existing testing equipment is large in size and expensive, and it is generally difficult for small grassroots hospitals to afford it. [0003] Due to its high sensitivity and high specificity, chemiluminescent immunoassay has basically replaced radioimmunoassay and enzyme-linked immunoassay, and has become the most widely used immunoassay in the field...
