Abstract
The present application relates to biological detection, in particular to a microfluidic chip and its operation method and use. The microfluidic chip comprises a lower shell, the lower shell comprising a reaction cell, a flow guide groove and a waste liquid pool formed on the inner surface of the lower shell and communicating with each other; a chip body arranged in the chip area of the reaction cell; an upper shell comprising a sample inlet hole penetrating through the upper shell and corresponding to the sample inlet end of the reaction cell, a gas permeation hole penetrating through the upper shell and corresponding to the waste liquid pool, and a gas discharge groove formed on the outer surface of the upper shell and communicating with the gas permeation hole. The microfluidic chip of the present application has the functions of preventing pollution, reliable detection, sensitivity, rapidness, simple structure and low price.
