An electrochemiluminescence biosensor for sulfadimethoxine detection based on enzymatic DNA walker-activated CRISPR/Cas12a cascade for signal enhancement.
Sulfadimethoxine (SDM) is a widely used veterinary antibiotic. Its residues in food and the environment may cause bacterial resistance and threaten human health. In this study, a novel electrochemiluminescence (ECL) biosensor with signal amplification was developed for the sensitive detection of SDM. A g-C3N4@Au compos...
