The Development of a Selective Colorimetric Sensor for Cu<sup>2+</sup> and Zn<sup>2+</sup> in Mineral Supplement with Application of a Smartphone Paper-Based Assay of Cu<sup>2+</sup> in Water Samples
Herein, we developed a colorimetric method for the determination of Cu<sup>2+</sup> and Zn<sup>2+</sup> using NBD-G as a novel selective metal sensor. NBD-G was easily synthesized by a nucleophilic substitution reaction between 4-chloro-7-nitro-2,1,3-benzoxadiazole (NBD-Cl) a...
