Title (EN) METAL-ORGANIC FRAMEWORKS AS ION-TO-ELECTRON TRANSDUCERS AND DETECTORS
(FR) CADRES MÉTALLO-ORGANIQUES EN TANT QUE TRANSDUCTEURS IONS-ÉLECTRONS ET DÉTECTEURS
Abstract:
(EN) Embodiments of the present disclosure pertain to ion-selective electrodes that include a metal-organic framework and an electrode surface. The metal-organic framework is associated with the electrode surface in a manner that forms an interface between the metal-organic framework and the electrode surface. Additional embodiments pertain to methods of detecting an ion in a sample by associating the sample with the ion- selective electrodes of the present disclosure. The metal-organic frameworks of the ion-selective electrodes mediate ion-to- electron transduction through the interface between the metal-organic frameworks and the electrode surface. Thereafter, the presence or absence of the ion in the sample is detected by detecting a change in potential of the ion-selective electrode and correlating the change in the potential to the presence or absence of the ion. The metal organic frameworks may simultaneously mediate ion sensing and ion-to-electron transduction through the interface between the metal-organic frameworks and the electrode surface.
(FR) Des modes de réalisation de la présente invention concernent des électrodes sélectives d'ions qui comprennent un cadre métallo-organique et une surface d'électrodes. Le cadre métallo-organique est associé à la surface d'électrodes de manière à former une interface entre le cadre métallo-organique et la surface d'électrodes. D'autres modes de réalisation concernent des procédés de détection d'un ion dans un échantillon par l'association de l'échantillon avec les électrodes sélectives d'ions de la présente invention. Les cadres métallo-organiques des électrodes sélectives d'ions assurent la médiation de la transduction ions-électrons à travers l'interface entre les cadres métallo-organiques et la surface d'électrodes. Puis, la présence ou l'absence de l'ion dans l'échantillon est détectée par la détection d'un changement de potentiel de l'électrode sélective d'ions et par la corrélation du changement du potentiel à la présence ou à l'absence de l'ion. Les cadres métallo-organiques peuvent induire simultanément la détection d'ions et la transduction d'ions-électrons à travers l'interface entre les cadres métallo-organiques et la surface d'électrodes.
