Nucleic acid detection disc and nucleic acid detection device

A nucleic acid detection disc includes a detection chip and a laser emission device. The detection chip includes a first cover plate, a spacer layer and a second cover plate. The first cover plate. The spacer layer and the second cover plate are surrounded to form a channel. The channel is used to carry the detection solution so that the detection solution can carry out nucleic acid amplification reaction in the channel to obtain nucleic acid amplification products. An observation window is provided in the first cover plate. The laser emission device is arranged on an outside of the channel, which is used to emit laser towards the channel. The laser is used to irradiate the product liquid beads to send out fluorescent signals. The observation window is used to observe the fluorescent signals. The nucleic acid detection disc provided by the invention can be used for instant quantitative fluorescence detection in the amplification process, with high detection efficiency, low cost, and strong flexibility.
