Construction of two fluorescence aptasensors with RecJf exonuclease-induced signal amplification for detecting aflatoxin B1.
Aflatoxin contamination, especially aflatoxin B1 (AFB1), is a major global health concern. There is an urgent need to develop rapid, highly sensitive and specific sensing platforms. In this study, two fluorescence aptasensors were developed for AFB1 detection. The first used quantum dots (QDs) combined with aptamers as...
