Abstract

The invention relates to a reagent concentration responsive microfluidic cell culture chip and a preparation method thereof. A microstructure and a microchannel are arranged on the surface of the microfluidic chip; the surface of the microchannel is modified by using bovine serum albumin cells; the cells are implanted in the microchannel by utilizing the laminar flow phenomenon between liquid flow under the drive of gravity generated by liquid difference between a solution inlet and a solution outlet; and cell culture solutions of biological reagents with different concentrations are added into the solution inlet at last. The microfluidic chip can be used for making a research on the influence of reagent concentration change on cell culture so as to lay a foundation for cell biology research, and is mainly applied to the related fields of cell biology, genetics, drug screening and the like. The microfluidic chip is simple to operate, can be used for finishing cell implantation and culture, reducing the usage amount of reagents and samples, simplifying the cell implantation process and making a research on the influence of reagent concentration change on cell culture, and has the characteristics of being portable, economic, quick, efficient and accurate, thereby providing a brand-new cell culture and analysis technology for cell biology research.

Description

technical field

[0001] The invention relates to a reagent concentration-responsive microfluidic cell culture chip and a preparation method thereof. The surface of the microfluidic chip has a microstructure and a microchannel, and the surface of the microchannel is modified with bovine serum albumin molecules. Driven by the gravity caused by the liquid difference between them, the laminar flow phenomenon between the liquid flows is used to realize the implantation of cells in the microchannel, and finally, cell culture solutions with different concentrations of biological reagents are added from the solution inlet to realize the change of reagent concentration. The impact on cell culture lays the foundation for the study of cell biology, and is mainly used in related fields such as cell biology, genetics, and drug screening. Background technique

[0002] In the late 1980s, in order to establish a culture system more similar to the in vivo environment and make the in vitro env...
