Embodiment

[0054] Embodiment: Taking the manufacture of a quincunx-shaped microfluidic chip and the detection of nitrite as examples, the manufacturing process mentioned in the present invention is further described.

[0055] figure 1 The three-dimensional model of the designed quincunx-shaped microfluidic chip substrate 1 is shown, and the three-dimensional model file is generated as an STL format file, and the obtained STL format file is imported into the three-dimensional printing software, and the printing parameter filling rate is set to 60. Connect to the computer, start the FDM three-dimensional printer, control the FDM three-dimensional printer to work through the computer, and start the printing process of the microfluidic chip substrate 1. Existing printing materials can be selected, such as polylactic acid (PLA), acrylonitrile-butadiene-styrene copolymer (ABS), etc., and polylactic acid is selected in this embodiment. After the printing is completed, the PLA microfluidic chip...

Abstract

The invention discloses a micro-fluidic chip assembly. The micro-fluidic chip assembly comprises a micro-fluidic chip and a cover plate covering the micro-fluidic chip, wherein a central sample adding port, multiple peripheral sample adding ports surrounding the central sampling adding port as well as runners communicating the multiple peripheral sample adding ports with the central sample adding port are formed in the micro-fluidic chip; through holes corresponding to the central sample adding port and the peripheral sample adding ports are formed in the cover plate; the micro-fluidic chip is in rotation fit with the cover plate, the cover plate is provided with a sample adding station for ensuring all the sample adding ports in the micro-fluidic chip to be correspondingly communicated with the through holes as well as a packaging station for plugging all the peripheral sample adding ports; a shifting piece is arranged between the micro-fluidic chip and the cover plate and used for covering the central sample adding port when the cover plate is located at the packaging station. The micro-fluidic chip assembly is simple in overall structure, convenient to use, capable of switching working states of the micro-fluidic chip only through simple rotation, very convenient to package and open and high in practicability.

Description

technical field [0001] The invention relates to the technical field of microfluidic chips, in particular to a microfluidic chip component. Background technique [0002] Microfluidic chip, also known as lab-on-a-chip, is a technology that manipulates fluids on a micron scale. The technology shrinks the basic functions of chemical and biological laboratories onto a chip only a few square centimeters in size. Through the intersection of analytical chemistry, micro-electromechanical processing, computer, electronics, materials department, biology, medicine and other disciplines, the miniaturization, automation, integration and portability from sample processing to detection are realized. The microfluidic chip has the characteristics of flexible combination and large-scale integration of various unit technologies, so that a large amount of information can be obtained with a small amount of samples, and it is more likely to surpass a single analysis function and become an overall...
