摘要:

脱氧核酶是通过体外筛选技术得到的具有催化功能的单链寡核苷酸分子. 随着体外筛选技术的发展, 越来越多的脱氧核酶被筛选出来. 其中, 靶向细菌的具有RNA切割作用的脱氧核酶(RNA-cleaving DNAzyme, RCD)同时拥有分子识别和催化RNA裂解的功能, 且具有设计灵活、 易于制备和修饰、 成本低廉等优势, 在致病菌检测领域获得了广泛的关注和应用, 为致病菌的早期发现和预防提供了全新的分子工具. 本文系统总结了RCD在致病菌检测中的研究和应用, 并对其面临的问题和未来发展前景进行了展望.

Abstract:

DNAzymes, produced through in vitro selection process, are single-stranded oligonucleotides that have catalytic functions. With the development of in vitro selection technology, more and more DNAzymes have been selected. Among them, RNA-cleaving DNAzyme(RCD) has the functions of molecular recognition and catalytic signal amplification, and has the advantages of flexible design, easy preparation and low modification cost, etc., which has gained widespread attention and application in the field of detection of pathogenic bacteria, providing a new molecular tool for early detection and prevention of pathogenic bacteria. In this paper, the research and application of RNA-cleavage deoxyribozyme in the detection of pathogenic bacteria were systematically summarized, and the problems and future development prospects of RNA-cleavage deoxyribozyme were also prospected.

Key words: DNAzyme, RNA-cleaving, Detection, Pathogenic bacteria
