Cl (tppz = 2,3,5,6-tetra(2′-pyridyl)pyrazine) including an Fe(

The catalytic degradation property in the assay was necessary for making the detecting system reversible, which the traditional indicator displacement assays could never achieve. After the realization of this new property, silica-gel-based solid-supporting complex
