The invention relates to a nicking endonuclease-based netted rolling cycle amplification system and a use thereof. Based on the existing second-generation hyperbranched rolling cycle amplification technology, the amplification system utilizes a special endonuclease which is nicking endonuclease Nb.BsrDI so that a third-generation rolling cycle amplification technology which is a netted rolling cycle amplification (NGCA) technology is produced. Intensity of fluorescence signals produced by the netted rolling cycle amplification is increased with increasing of a target DNA concentration, is obviously stronger than that of fluorescence signals produced by linear rolling cycle amplification and hyperbranched rolling cycle amplification and has a detection limit of 0.1fM. Compared with the first-generation linear rolling cycle amplification and the second-generation hyperbranched rolling cycle amplification, the nicking endonuclease-based netted rolling cycle amplification system retains the prior art advantages in operationality, use cost and amplification time, further realizes signal amplification based on the prior art thereby providing good technical conditions for ultralow-abundance nucleic acid sample analysis and detection, and has a wide application prospect.
