A Simple and Label-Free Detection of As<sup>3+</sup> using 3-nitro-L-tyrosine as an As<sup>3+</sup>-chelating Ligand

A simple and rapid As<sup>3+</sup> detection method using 3-nitro-L-tyrosine (N-Tyr) is reported. We discovered the specific property of N-Tyr, which specifically chelates As<sup>3+</sup>. The reaction between As<sup>3+</sup> and N-Tyr induces a prompt color chang...
