Abstract

Under the two-photon excitation, upconversion luminescent “INHIBIT” and “OR” logic gates of water-dispersed CdTe quantum dots (QDs) were constituted by conjugating the QDs with dopamine. This facilitated the development of a novel QDs-based upconversion luminescent probe for efficient turn-on sensing of glutathione.
