Target-responsive aptamer-cross-linked hydrogel sensors for the visual quantitative detection of aflatoxin B1 using exonuclease I-Triggered target cyclic amplification

Target-responsive aptamer-cross-linked hydrogel sensors for the visual quantitative detection of aflatoxin B1 using exonuclease I-Triggered target cyclic amplification

For the on-site detection of aflatoxin B1 (AFB1), a DNA hydrogel was prepared as a biosensor substrate, while an AFB1 aptamer was used as the recognition element. An AFB1-responsive aptamer-cross-linked hydrogel sensor was constructed using an enzyme-linked signal amplification strategy; AFB1 binds...
