The widespread occurrence of hydrazine residues in the environment, including in water, soil, and organisms, is a potential health threat to humans. Therefore, the development of an efficient method for the detection of hydrazine in environmental samples is highly desirable although it poses a significant challenge. In this study, we designed and synthesized a series of naphthalene-based fluorescent dyes through structural engineering and developed a novel probe for hydrazine detection. The probe could provide a distinct fluorescence response toward hydrazine in aqueous solution with high sensitivity and selectivity. Moreover, paper-based test strips can be easily fabricated using this probe, enabling the portable on-site detection of hydrazine with the aid of a smartphone. Furthermore, we demonstrated that this probe is capable of recognizing hydrazine in various environmental samples, including water, soil, plants, and zebrafish embryos. This research provides a promising tool for the detection of hydrazine in the environment.
肼残留物在包括水、土壤和生物体在内的环境中广泛存在，这对人类健康构成了潜在威胁。因此，尽管开发一种高效的环境样品中肼的检测方法面临重大挑战，但这一需求十分迫切。在本研究中，我们通过结构工程设计并合成了一系列基于萘的荧光染料，并开发了一种用于肼检测的新型探针。该探针能够在水溶液中对肼产生明显的荧光响应，具有高灵敏度和选择性。此外，使用该探针可以轻松制备纸质测试条，借助智能手机实现肼的便携式现场检测。此外，我们证明了该探针能够识别包括水、土壤、植物和斑马鱼胚胎在内的各种环境样品中的肼。这项研究为环境中肼的检测提供了一种有前景的工具。
