Among the various aflatoxin B1 (AFB1) assays, performing accurate detection is difficult because false positives and negatives are frequent due to limited sensitivity, expensive equipment, or inadequate pretreatment during operation. Here, an "off-on" switch-type electrochemiluminescence (ECL) aptasensor armed with cobalt-sulfur quantum dots was encapsulated in hollow cobalt-layered double hydroxide nanocages as enhanced luminescent probe (Co-LDH@QDs), a ferrocene-modified aptamer (Fc-APT) used quencher. In general, when Fc-APT hybridized complementary DNA modified nanotetrahedron, electron transfer between ferrocene Co-LDH@QDs facilitated, leading efficient quenching of ECL intensity into "off" state absence AFB1. presence AFB1, increased increasing AFB1 concentration after specifically recognized that detached from electrode interface achieve "on" state. The linear range proposed for 0.1 pg mL

Abstract Electrochemical technology provides unique opportunities to create an environment‐friendly and sustainable chemical industry. Nano‐electrochemistry offers valuable insights into the comprehension of electrochemical mechanisms behaviors at nanoscale, as opposed complex ensemble systems. Despite use various analytical tools, such nanopore scanning probe microscopy, for nano‐electrochemical research, direct operando high‐throughput spatially resolved measurements remain challenging. Electrochemiluminescence (ECL) is reactions‐dependent luminescence process without external light sources. Coupled with a microscopy configuration, novel imaging methodology ECL (ECLM), developed. ECLM, due its distinctive mode, holds considerable potential in field nano‐electrochemistry. This review will initially present overview basic principles ECL. The next section describe design ECLM apparatus discuss diverse applications Finally, challenges outline prospects further development technique summarized.
