Chemosensor 1 was synthesized by the reaction of octopamine with 2,3-dihydroxybenzaldehyde. Sensor 1 determined iron with an obvious color change from pale yellow to brown in nearly-pure water. The detection limits (0.55 and 0.25 μM) for Fe²⁺ and Fe³⁺, respectively, were far lower than the EPA (Environmental Protection Agency) guideline concentration for drinking water (5.37 μM). In addition, 1 could be employed to quantify iron in environmental water samples. Moreover, sensor 1 exhibited different fluorescence emissions in response to zinc (green) and cadmium (blue). The binding structures and sensing mechanisms of 1 for iron, zinc and cadmium were proposed from various spectroscopic studies and theoretical calculations.

比色法检测铁，荧光法检测锌和镉，其中包含生物友好型章鱼胺的化学传感器†

化学传感器1是通过章鱼胺与2,3-二羟基苯甲醛的反应合成的。传感器1在几乎纯净的水中确定铁具有从浅黄色到棕色的明显颜色变化。Fe ²⁺和Fe ³⁺的检出限（0.55和0.25μM）远低于EPA（环境保护署）的饮用水标准浓度（5.37μM）。另外，可以采用1定量环境水样品中的铁。此外，传感器1响应于锌（绿色）和镉（蓝色）表现出不同的荧光发射。所述结合结构和感测机构1 各种光谱学研究和理论计算提出了用于铁，锌和镉的方法。
