Abstract

A simple and facile strategy was developed for regulating the luminescence of Tb³⁺ sensitized by DNA, in which Ag⁺ and cysteine (Cys) act as activators. The Ag⁺/Cys-mediated reversible luminescence changes in the Tb³⁺-DNA sensing system enabled the design of a DNA INHIBIT logic gate and a H₂O₂ sensor in a time-resolved luminescence format.
