Description

technical field

[0001] The invention belongs to the field of detection equipment, and relates to a biochemical and immune detection device, in particular to a scattering turbidimetric detection microfluidic chip and a biochemical immune machine using the chip. Background technique

[0002] Microfluidic chip technology is a new technology for precisely manipulating and controlling nanoliter and picoliter-level fluids (biological sample fluids) in micron-scale flow channels. The application of this technology can integrate sample preparation, The basic operation units such as reaction, separation, detection, cell culture, sorting, and lysis are integrated or basically integrated on a chip of several square centimeters (or even smaller), and a network of microfluidic channels is formed to control the flow of fluid throughout the system. A technology platform used to replace the various functions of conventional chemical or biological laboratories. The basic feature and biggest ...
