In the presence of AFB<sub>1</sub>, the probe preferentially combined with AFB<sub>1</sub> rather than binding to the circular template, inhibiting the initiation of RCA process. The detection limit of the proposed method was as low as 6.6 nM, and the linear dynamic response range was four orders of magnitude wide. Besides, it revealed excellent specificity for AFB<sub>1</sub> and high-quality detection performance in food samples.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusion</h3>\u0000 \u0000 <p>The presented detection method was simple, rapid, and economical, which indicated a promising application in food safety monitoring.</p>\u0000 </section>\u0000 </div>","PeriodicalId":93795,"journal":{"name":"JSFA reports","volume":"3 8","pages":"346-353"},"PeriodicalIF":0.0,"publicationDate":"2023-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47441120","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
