The nucleic acid detection system provided in this application includes a Cas protein, a first RNA portion, and a second RNA portion. The first and second RNA portions can interact to form a functional crRNA in the presence of the target nucleic acid. This functional crRNA can form a complex with the Cas protein and activate the trans-cleavage activity of the Cas protein. This invention creatively separates the crRNA into independent first and second RNA portions, whose binding affinity to Cas12a is significantly weaker than that of the full-length crRNA, thereby reducing the cis and trans-cleavage activity of Cas12a. This low-activity state provides a sufficient time window for the nucleic acid amplification reaction, allowing the amplification products to accumulate. When the target amplification product accumulates to a sufficient concentration, it can induce the separated crRNA to assemble with Cas12a into an active complex, thereby activating trans-cleavage and achieving an intelligent response of amplification-driven cleavage. The entire process requires no physical isolation, chemical inhibition, or programmed temperature control, truly achieving closed-tube, unmanned detection.
