Multifunctional AuAgPt Nanoframes for a Stimuli-Responsive Electrochemiluminescence Aptasensor

further activates DNAzyme to cut the substrate strand (S-DNA), which causes AuAgPt NFs to detach from the electrode surface and the ECL signal to significantly decrease. Under optimal conditions, the proposed ECL aptasensor exhibits high sensitivity with a limit of detection (LOD) of 0.11 fg/mL in the range of 1 fg/mL to 1 μg/mL for AFB1 detection.
