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

“…37,38 Wang et al developed a novel double-signal amplification cathode ECL aptamersensing platform based on Eu-PCP to achieve sensitive detection of ZEN in corn. 39 The proposed ECL sensor shows a large linear range of 0.001-200 μg kg −1 and a detection limit of 9.75 × 10 −5 μg kg −1 . According to the Chinese standard GB 2761-2017, the maximum content of zearalenone in cereals and their products is 60 μg kg −1 .…”

Novel Ultralow-Potential Electrochemiluminescence Aptasensor for the Highly Sensitive Detection of Zearalenone Using a Resonance Energy Transfer System

“…At present, numerous analytical methods have been employed to analyze ZEN, such as thin-layer chromatography, 7 high-performance liquid chromatography, 8 fluorescence (FL), 9 enzyme-linked immunosorbent assay, 10 and electrochemiluminescence (ECL). 11,12 Among these methods, ECL integrates the merits of electrochemistry and chemiluminescence and has attracted extensive attention in the area of biosensors. 13−17 A common problem in the ECL technology is the triggering potential of conventional ECL luminophores, such as the πconjugated molecule 3,4,9,10-perylene tetracarboxylic acid, 18 quantum dots, 19 and Ru(bpy) 3 2+ , 20 which usually need a highly negative potential to produce a strong ECL intensity.…”

“…As a Group 3B carcinogen, excessive ZEN seriously affects the safety of food, resulting in enormous economic loss and major threat to human health. − Thus, it is crucial to design a reliable and accurate method for ultrahighly sensitive and efficient detection of ZEN. At present, numerous analytical methods have been employed to analyze ZEN, such as thin-layer chromatography, high-performance liquid chromatography, fluorescence (FL), enzyme-linked immunosorbent assay, and electrochemiluminescence (ECL). , Among these methods, ECL integrates the merits of electrochemistry and chemiluminescence and has attracted extensive attention in the area of biosensors. − …”

Screening-Capture-Integrated Electrochemiluminescent Aptasensor Based on Mesoporous Silica Nanochannels for the Ultrasensitive Detection of Deoxynivalenol in Wheat

“…Electrochemiluminescence (ECL) is an electrochemical detection technology that combines electrochemistry and chemiluminescence . Because of its characteristics of high sensitivity and simple operation, ECL has attracted considerable attention in the field of biosensing. − Although a few studies have been recently conducted on the use of ECL sensors to detect DON, only one of them was based on an ECL aptasensor. , You et al prepared Ti 3 C 2 dots/Ti 3 C 2 nanosheets (TDTN) using a solvothermal method based on zero-dimensional Ti 3 C 2 dots and two-dimensional Ti 3 C 2 nanosheets . Using TDTN as the ECL emitter, an ECL biosensor was constructed and successfully applied for detecting DON in milk samples.…”
