Embodiment Construction

[0024] The present invention provides a microfluidic chip and its preparation method and application. In order to make the purpose, technical solution and effect of the present invention more clear and definite, the present invention will be further described in detail below. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0025] Because in the DOE test implementation part, the existing technology is to manually add the combination of factors (samples to be analyzed), which is time-consuming and labor-intensive and prone to errors. Based on this, an embodiment of the present invention provides a microfluidic chip, which includes a sample dispersion layer and a sample inlet layer stacked above the sample dispersion layer, and the sample dispersion layer includes several sample dispersion layers stacked in sequence. A sublayer, the sample inlet layer is provided with a samp...

Abstract

The invention discloses a microfluidic chip and its preparation method and application, wherein the microfluidic chip includes a sample dispersion layer and a sample inlet layer stacked above the sample dispersion layer, and the sample dispersion layer includes Several sample dispersing sublayers are stacked in sequence, the sample inlet layer is provided with sample dropping holes, and the sample dispersing sublayers are all provided with sample receiving holes corresponding to the sample dropping holes, the Several sample dispersion holes are arranged on each of the sample dispersion sub-layers, and a preset sample channel is arranged between the sample dispersion holes and the sample receiving hole. The microfluidic chip provided by the present invention only needs to add the sample to be analyzed in the sample dropping hole of the microfluidic chip, and the sample combination according to the test plan can be automatically realized inside the microfluidic chip to complete the sample combination. The addition of , greatly reduces the probability of error, and is more convenient, fast and accurate.

Description

technical field [0001] The invention relates to the field of biochemical applications, in particular to a microfluidic chip and its preparation method and application. Background technique [0002] Design of experiment (DOE) is a kind of scientific research, which is a commonly used method of arranging experiments in production and management. This method can use as few experiments as possible to screen out which factors among various factors that affect the experimental results The impact is significant, and through data processing and analysis, the best combination of experimental conditions can be further determined. Experimental design includes three steps: protocol design, experiment implementation and result analysis. At present, there are many methods for the design of the experimental design that can be used for reference. The design method can be selected according to the purpose of the experiment; as for the implementation of the experiment, the existing method is...
