Abstract

The invention provides a microfluidic chip and its preparation method and application. The microfluidic chip is composed of 2 concentration gradient generating units, 1 to 10 mixing units and cell culture units, and the entrance of the mixing unit is a concentration gradient generating unit. The drug solution outlet of the unit, the uppermost end of the concentration gradient generation unit is the drug solution or culture medium inlet. The microfluidic chip is integrated with a concentration gradient generating unit and a mixing unit, which can finally generate different levels of concentration mixing of various drugs to stimulate cells fixed in a specific cell culture unit, and it is possible to visually study the effect of cells during growth under a microscope. The reaction of multi-drug multi-level combination provides new ideas and new research technologies for large-scale drug combination screening. It is mainly used in related fields such as cell biology, genetics and drug screening. A new tool for cell analysis.

Description

technical field [0001] The invention belongs to the technical field of microfluidic chips, in particular to a microfluidic chip and its preparation method and application. Background technique [0002] Cell culture is an indispensable and important step in the drug development process. Conventional cell culture has many deficiencies in high-throughput drug screening, and it is rarely involved in multi-level drug combination screening. There is no high-throughput screening platform. The multi-level combination of multiple drugs can more truly reflect the actual drug use of people, study the impact of drug combination on cells, and simulate the interaction between drugs in human tissues, which is also conducive to the rapid screening of the efficacy and effectiveness of new drug drug combination. toxicity. Therefore, the development of a convenient, fast, efficient, and low-cost drug combination screening technology is an urgent need in the fields of drug screening and cell ...
