  Cu(II) detection in the presence of main group heavy metal ions and d-, f- and g-element interferents relies on a colorimetric chelating complex between 3-hydroxy-5-nitrobenzaldehyde-4-hydroxybenzoylhydrazone (3-HNHBH) and Cu(II). Derivatives and entrapped forms of the probe were aligned with the methods of analysis, featuring spectrophotometric, reflectometric, lateral flow, microfluidic, lab-on-paper, positional array, dynamic array, flow cytometry and tandem stage devices. A remotely operating software capable of DFT calculations predicted the observed detection limit of 0.34 μg L−1 (<5 nM) as well as high selectivity towards copper ions in the presence of competing Zn+2 and Ni+2. The probe was readily regenerated against metal complexation by using a 0.5 M HCl solution, indicating its feasibility to be a re-usable sensor for the convenient detection of copper ions in water-organic media. The influence of metal interference, pH and solvents on the selectivity and regeneration of the ligand was incorporated in an algorithm providing decision support to the analyst via smartphone, laptop and other multimedia.

  在存在主族重金属离子以及 d-、f- 和 g 元素干扰物的情况下，铜（II）的检测依赖于 3-hydroxy-5-nitrobenzaldehyde-4-hydroxybenzoylhydrazone (3-HNHBH) 与铜（II）之间的比色螯合复合物。探针的衍生物和夹带形式与分析方法一致，包括分光光度法、反射法、横向流动法、微流体法、纸上实验室法、定位阵列法、动态阵列法、流式细胞仪和串联台装置。可进行 DFT 计算的远程操作软件预测了 0.34 μg L-1 （<5 nM）的检测限，以及在存在竞争性 Zn+2 和 Ni+2 的情况下对铜离子的高选择性。通过使用 0.5 M HCl 溶液，该探针很容易在金属络合作用下再生，这表明它是一种可重复使用的传感器，可方便地检测水有机介质中的铜离子。金属干扰、pH 值和溶剂对配体选择性和再生的影响已被纳入一种算法，通过智能手机、笔记本电脑和其他多媒体为分析人员提供决策支持。
