A Simple and Label-Free Detection of As(3+) using 3-nitro-L-tyrosine as an As(3+)-chelating Ligand
A simple and rapid As(3+) detection method using 3-nitro-L-tyrosine (N-Tyr) is reported. We discovered the specific property of N-Tyr, which specifically chelates As(3+). The reaction between As(3+) and N-Tyr induces a prompt color change to vivid yellow, concomitantly increasing the absorbance at 4...
