Description

technical field [0001] The invention relates to the field of microfluidic technology, in particular to a microfluidic combined chemical reaction chip. Background technique [0002] Combinatorial chemistry (combina torialchemist) is a new discipline that has just emerged in the past ten years. After a short period of more than ten years, especially the development of the past six or seven years, combinatorial chemistry has penetrated into many fields of chemistry such as medicine, organic matter, materials, and analysis. With the improvement of automation level, combinatorial chemistry has become the most active in the chemical field. one of the fields. The emergence of combinatorial chemistry has greatly accelerated the speed of compound synthesis and screening. Some people have made such statistics: 1 chemist with a workload of 2 to 6 weeks using combinatorial chemistry methods requires 10 chemists to spend a year with traditional chemical methods To be done. The emergen...
