Hypochlorite (ClO) and gallium (Ⅲ) ions (Ga) have extensive applications in various human industries and daily activities. However, their inherent toxicity poses significant risks to environmental preservation and human well-being. Hence, the development of reliable and handy detection tools for ClO and Ga in the environment and food is crucial. In this study, a ratiometric fluorescent probe was prepared based on benzothiazolaldehyde and pyridine-2-carboxylic acid hydrazide, which exhibited exceptional performance characteristics for the selective detection of ClO and Ga. These features include high specificity, low detection limits (0.28 μM for ClO, 0.13 μM for Ga), mild pH conditions (pH 4-11 for ClO, pH 6-11 for Ga), fast response time (within 30 s), as well as versatile applicability across different matrices such as water, soil, food, and plant samples. Additionally, this probe can be used with a smartphone color recognition app. The probe offers a convenient and effective tool for the detection of ClO and Ga, demonstrating its potential application value in environmental monitoring and food safety.
次氯酸盐 (ClO) 和镓 (Ⅲ) 离子 (Ga) 在人类的各个行业和日常活动中都有广泛的应用。然而，它们固有的毒性对环境保护和人类福祉构成了重大威胁。因此，开发可靠且便捷的环境和食品中 ClO 和 Ga 的检测工具至关重要。在这项研究中，我们基于苯并噻唑醛和吡啶-2-羧酸酰肼制备了比率荧光探针，该探针对 ClO 和 Ga 的选择性检测具有优异的性能特点。这些特点包括高特异性、低检测限（0.28 μM 用于 ClO，0.13 μM 用于 Ga）、温和的 pH 条件（ClO 的 pH 为 4-11，Ga 的 pH 为 6-11）、快速的响应时间（在 30 s 内）以及在不同基质（如水、土壤、食物和植物样本）中具有广泛的适用性。此外，该探针可以与智能手机颜色识别应用程序配合使用。该探针为 ClO 和 Ga 的检测提供了一种便捷有效的工具，展示了其在环境监测和食品安全方面的潜在应用价值。
