摘要：

A multifunctional electrochemiluminescence (ECL) coreaction accelerator, AuAgPt nanoframes (NFs), is described for use in an ECL aptasensor for highly sensitive aflatoxin B1 (AFB1) detection. As a signal quencher, the broad UV-vis absorption spectrum of AuAgPt nanosheets (NSs) overlaps the ECL emission spectrum of g-C(3)N(4)@Au, triggering an ECL resonance energy transfer (ECL-RET). By the adjustment of the dosage of hydrogen peroxide (H(2)O(2)), the AuAgPt NSs are transformed into AuAgPt NFs because H(2)O(2) etches Ag in AuAgPt NSs into Ag(+),...
