Dual Signal-Enhanced Electrochemiluminescence Strategy Based on Functionalized Biochar for Detecting Aflatoxin B1.

ABSTRACT: Metal-organic frameworks (MOFs) are often used as carriers in the preparation of electrochemiluminescent (ECL) materials, and ECL materials stabilized in the aqueous phase can be prepared by encapsulating chromophores inside MOFs by an in situ growth method. In this study, nanocomposites MIL-88B(Fe)-NH₂@Ru(py)₃²⁺ with excellent ECL response were prepared by encapsulating Tris(2,2'-bipyridine)ruthenium dichloride (Ru(py)₃²⁺) inside MIL-88B(Fe)-NH₂ using the one-step hydrothermal method. MIL-88B(Fe)-NH₂ possesses abundant amino groups, which can accelerate the catalytic activation process of K₂S₂O₈, and its abundant pores are also conducive to the enhancement of the transmission rate
