Abstract

The invention discloses a magnetic particle chemiluminescence micro-fluidic chip. The micro-fluidic chip comprises a top plate (1) and a bottom plate (2), the top plate (1) comprises an air pump (3), a sample adding opening (4), a sample filling area (12), a marking ligand storage pool (5) and a sample mixing area (13). The bottom plate (2) comprises a filter area (6), a magnetic particle coating area (7), a washing area (14), a detecting area (8), a washing liquid storage pool (9), a light-emitting substrate storage pool (10) and a liquid release channel (16). The top plate and the bottom plate both comprise liquid sensing devices, and the liquid sensing devices are used for determining the flowing state of liquid in the micro-fluidic chip and whether bubbles are mixed into the micro-fluidic chip.

Description

technical field

[0001] The invention belongs to the technical field of microfluidic chip chemiluminescence immunoassay detection, and in particular relates to a chip which utilizes magnetic particle chemiluminescent technology and microfluidic chip technology to realize highly sensitive quantitative detection of analytes. Background technique

[0002] At present, there are two main development trends for in vitro diagnostics (IVD): one is automation and integration, that is, the use of fully automated and highly sensitive large-scale instruments and equipment in the central laboratory of a large hospital to achieve high-precision disease analysis and diagnosis ; Another kind of miniaturization and bedside, that is, to realize rapid analysis and diagnosis on the spot through small and simple handheld devices. Small hospitals with insufficient funds and small sample sizes are not suitable for purchasing large and expensive equipment. At this stage, small rapid detection equip...
