Abstract

The automatic solution draining device for automatic DNA calculating machine includes one reaction tank, plastic hoses, six electromagnetic clamps, one piston pump, two T-pipes, two solution cavities, one waste liquid tank, and electrochemical biochips connected together. The present invention has simple structure and reliable operation, and can meet the requirement of no residue and no leakage of solution draining treatment during DNA calculating reaction.

Description

technical field [0001] The invention relates to a device in the technical field of bioengineering, in particular to a DNA reaction solution automatic discharge device. Background technique [0002] DNA (deoxyribonucleic acid) computing technology, simply put, is based on the unique combination of DNA double helix structure, artificially recombines and arranges the four base pairs of DNA molecules, so as to realize the function of numerical and logical operations. The medium to complete this operation is a DNA chain, so it is called DNA computing. The process of DNA computing is the process of placing DNA molecules in the reaction pool to make them react and process in a specific solution. During DNA calculation, solutions such as sample solution, buffer, ligase and sodium hydroxide need to be added to the reaction cell. In the reaction pool, the intermediate process waste liquid is generated first, and then the final result solution to be tested; after a calculation is com...
