Electrochemiluminescence resonance energy transfer immunoassay based on a porphyrin metal–organic framework and AuNPs/NSG for the sensitive detection of zearalenone

A novel electrochemiluminescence resonance energy transfer (ECL-RET) system using porphyrin metal-organic framework (PCN-222) as a novel donor and AuNPs/NSG nanocomposites as the acceptor has been designed as well as applied in an immunosensor for detecting zearalenone (ZEN) in grain.
