Establishment of fumonisin B1 detection method for catalytic fluorescence detection of aptamer-regulated carbon dots

develop aptamer-regulated CDs for detection of FB 1 by catalytic fluorescence. 2,2′-Dithiosalicylic acid was used to prepare carbon dots catalysing the fluorescence of TMB. Aptamer F10 can bind to FB 1 , restoring the catalytic capacity of CDs and increasing fluorescence.
