Abstract

Ethephon (ETH) is a plant growth regulator extensively utilized in agriculture, but its overuse is associated with several health issues. However, detecting ETH sensitively and easily in the field is challenging due to the complexity and time-consuming operation of current approaches. In this study, we synthesized aluminum-based metal-organic frameworks (CAU-1) as fluorescent probes for the detection of ETH in fruit. ETH exposure enhanced and shifted the light green fluorescence of CAU-1 to blue through high absorption of phosphate by electrostatic attraction. We observed a linear correlation between fluorescent intensity and ETH concentration ranging from 2 mg/L to 400 mg/L, with the lowest detection limit at 1 mg/L. This fluorescent analysis exhibited good selectivity towards ETH. To facilitate easy identification of samples in the field, we designed a fluorescent paper-based platform with a logic gate operation, allowing visual distinction of samples containing ETH. We applied this platform to monitor ETH in various fruits, including apples, pears, and tomatoes, through fluorescent spectrum, and visual detection. The platform offered simplicity, speed, ease of use and sensitivity, providing a promising future for ETH detection in agriculture.

利用铝基金属有机框架的纸质微传感器比色检测水果中的乙硫磷
乙硫磷(ETH)是一种在农业中广泛使用的植物生长调节剂,但其过度使用会带来一些健康问题。然而,由于目前的方法复杂且操作耗时,在田间灵敏、轻松地检测 ETH 具有挑战性。在这项研究中,我们合成了铝基金属有机框架(CAU-1)作为荧光探针,用于检测水果中的 ETH。暴露于 ETH 后,CAU-1 的浅绿色荧光通过静电吸引对磷酸盐的高吸收而增强并转变为蓝色。我们观察到荧光强度与 ETH 浓度(从 2 mg/L 到 400 mg/L)呈线性相关,最低检测限为 1 mg/L。这种荧光分析方法对 ETH 具有良好的选择性。为了便于在现场识别样品,我们设计了一种基于逻辑门操作的荧光纸平台,可以直观地区分含有 ETH 的样品。我们应用该平台通过荧光光谱和视觉检测来监测各种水果(包括苹果、梨和西红柿)中的 ETH。该平台操作简单、速度快、易于使用且灵敏度高,为农业中的 ETH 检测提供了广阔的前景。

期刊介绍: In 1985, the Journal of Science was founded as a platform for publishing national and international research papers across various disciplines, including natural sciences, technology, social sciences, and humanities. Over the years, the journal has experienced remarkable growth in terms of quality, size, and scope. Today, it encompasses a diverse range of publications dedicated to academic research. Considering the rapid expansion of materials science, we are pleased to introduce the Journal of Science: Advanced Materials and Devices. This new addition to our journal series offers researchers an exciting opportunity to publish their work on all aspects of materials science and technology within the esteemed Journal of Science. With this development, we aim to revolutionize the way research in materials science is expressed and organized, further strengthening our commitment to promoting outstanding research across various scientific and technological fields.
