A magnetic beads (MBs)–assisted fluorescence aptasensing approach based on dual DNA tweezers and magnetic separation was established for the detection of ochratoxin A (OTA) and fumonisin B 1 (FB 1 ). A dual DNA tweezers structure with four ends linked with fluorophores (FAM, ROX) and quenchers (BHQ...
