title: A ratiometric luminescent oxygen sensor based on a chemically functionalized quantum dot.
abstract: Nanoconjugates composed of CdSe-ZnS core-shell nanocrystals and pyrenyl ligands are shown to exhibit a double photoluminescence. Owing to the different response of the two emission signals towards oxygen, the nanocrystals function as high dynamic range ratiometric luminescent O(2) nanosensors.
