Colorimetric enzyme-linked immunosorbent assay utilizing 3'-3-5'-5-tetramethylbenzidine(TMB) as the chromogenic substrate has been widely used in the hospital for the detection of all kinds of disease biomarkers. Herein, we demonstrate a strategy to change this single-color display into dual-color responses to improve the accuracy of visual inspection. Our investigation firstly reveals that oxidation state of 3'-3-5'-5-tetramethylbenzidine (TMB(2+)) can quantitatively etch gold nanoparticles. Th ...[more]
