Electrochemiluminescence sensor for the detection of Amaranth Red based on ZnMnO2-accelerator and Luminol functionalized Ti3AlC2
The synthesis of self-supporting material ZnMnO₂ by electrospinning and high-temperature calcination is reported. A highly sensitive electrochemiluminescence (ECL) sensor for Amaranth Red (AR) detection was constructed using Luminol@Ti₃AlC₂ and ZnMnO₂ with multi-step signal amplification. Luminol-O2 served as the ECL probe with luminescent signal originating from its reaction with dissolved oxygen. Ti₃AlC₂ was introduced as the carrier to enhance the effective concentration of the ECL reagent and improve the signal. ZnMnO2 as the co-reaction promoter could further improve the ECL value. The highest signal was attributed to the combined catalytic action of Luminol@Ti3AlC2 and ZnMnO2. A new method for the detection of AR was developed due to the resonance energy transfer (RET) between Luminol and AR. Under optimal conditions, the response to AR exhibited a linear range from 5.0 × 10−15 to 5.0 × 10−5 mol·L−1. The sensor achieved satisfactory AR detection in candy samples.
