An automatic immunoassay system is provided to an automatic immunoassay apparatus and includes a well cartridge provided with a plurality of wells in which a tip mounted on the automatic immunoassay apparatus is sequentially dipped, a cartridge loading mechanism coupled to a lower portion of the well cartridge to couple the well cartridge to the holding plate, a light source unit disposed at one side of the cartridge unit to emit light to the wells, a sensing unit disposed at the other side of the cartridge unit to detect a fluorescence signal generated by light delivered to the wells, and an assay unit analyzing the fluorescence signals detected by the sensing unit.

The application belongs to the technical field of cell culture, and particularly relates to a method for determining the number of particles in a unit volume of liquid and application. The method comprises the following steps: (1) using a dye to dye the liquid to be measured, and sequentially dropping the dyed liquid to be measured and a chromatographic separation liquid at one end of filter paper, the particles in the liquid to be measured are dispersed on the filter paper under the action of capillary chromatography, and the number of particles in the liquid to be measured is obtained by naked-eye counting; (2) according to the volume of the liquid to be measured, the number of particles in a unit volume of liquid is calculated. The determination method of the application does not need to purchase expensive instruments, does not need to take photos and use image analysis software for auxiliary counting, breaks through the limitation that a blood cell counter cannot determine particles with a particle size greater than 100 mu m, and can complete the determination of the number of particles by naked-eye observation, which is simple, efficient and low in cost.

A microfluidic device includes multiple microfluidic assay units arranged on a substrate, with each assay unit including multiple scaffold regions each containing a three-dimensional scaffold with associated cells, and a media channel surrounding a fluid-permeable boundary portion of at least a second scaffold region, wherein a fluid-permeable interface between the media channel and the second scaffold region comprises a curved shape spanning an arc of more than 90 degrees. A third scaffold region may be provided. Boundaries between different scaffold regions, and between a scaffold region and the media channel, may include microposts that may be spaced apart in a curved configuration. A method for performing an assay utilizing such a device is further provided.

An inspection apparatus (10) includes an image capturing device (20), a memory module (32), a determination unit (33), and a notification unit (40). The image capturing device (20) is configured to capture images of a work area. The memory module (32) stores a first learning model (M1) trained through machine learning to output, when receiving image data captured by the image capturing device (20), an indicator that indicates whether an assembly state of a component is a correct assembly state. The determination unit (33) is configured to determine whether the assembly state is the correct assembly state for each assembly step based on an output result of the first learning model (M1). The notification unit (40) is configured to notify an operator of a determination result of the determination unit (33).
