With the projected climate change, traditional detection methods face limitations, and there is an urgent need for more accurate and efficient diagnostic techniques.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Objective<\/jats:title>\n                  <jats:p>The aim is to integrate Recombinase-aided Amplification (recombinase-aided amplification, RAA) and Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR) to establish a special CRISPR-Cas system for rapid, convenient, high sensitivity, and high specificity typing detection of DENV.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Methods<\/jats:title>\n                  <jats:p>CRISPR RNA (crRNA) and RAA primers were designed based on the whole genome of four DENV serotypes. A single-tube assay combining RAA with CRISPR-Cas13a technology was developed after optimizing reagent concentrations.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>The limit of detection (LoD) of DENV types 1\u20134 was 10\u00b3 copies\u00b7mL \u22121. No cross-reaction was observed between any of the DENV serotypes and the other three flaviviruses (Zika, West Nile, and Murray Valley encephalitis). The average sensitivity of one-step method was 95.8%, and the average specificity was 96.6%. Fluorescent signal intensities demonstrated a clear dose-dependent response, with the signal increasing as the sample concentration rose. This system can effectively distinguish non-target substances. Among them, one-step method has advantages in timeliness, ease of operation, and contamination control because it runs efficiently inside a tube and does not require the lid to be removed, but its sensitivity is relatively low. The two-steps method performs well in sensitivity.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusion<\/jats:title>\n                  <jats:p>In this study, we developed a novel method for rapid typing and detection of DENV using RAA and CRISPR-Cas13a in a single-tube homogeneous system.<\/jats:p>\n               <\/jats:sec>","DOI":"10.1093\/jambio\/lxaf070","type":"journal-article","created":{"date-parts":[[2025,3,18]],"date-time":"2025-03-18T02:42:06Z","timestamp":1742265726000},"source":"Crossref","is-referenced-by-count":8,"title":["Rapid and efficient CRISPR-based detection of dengue virus in a single-tube"],"prefix":"10.1093","volume":"136","author":[{"given":"Jiaye","family":"Zhong","sequence":"first","affiliation":[{"name":"Key Laboratory of Artificial Organs and Computational Medicine in Zhejiang Province, Shulan International Medical College, Zhejiang Shuren University , Hangzhou, Zhejiang ,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Juezhuo","family":"Li","sequence":"additional","affiliation":[{"name":"Wycombe Abbey School Hangzhou , Hangzhou 311261 ,","place":["P.
