TL;DR: In this article, a review examines methods of functionalizing porous carbon through direct incorporation of heteroatoms in the carbon synthesis, surface oxidation and activation, halogenation, sulfonation, grafting, attachment of nanoparticles and surface coating with polymers.

TL;DR: Electrodes with three-dimensionally ordered macroporous (3DOM) carbon as the intermediate layer between an ionophore-doped solvent polymeric membrane and a metal contact are presented as a novel approach to solid-contact ion-selective electrodes (SC-ISEs).

TL;DR: A comparison of the different techniques to characterize the solid contacts confirms that constant-current charge-discharge experiments offer an intriguing approach to assess the long-term stability of solid-contact ISEs but shows that their results need to be interpreted with care.

TL;DR: In this work, fluorous membrane matrixes were used to prepare silver ion-selective electrodes (ISEs) based on the most selective ionophores, that is, 1,3-bis(perfluorodecylethylthiomethyl)benzene, which provided much higher selectivities for Ag(+) over many alkaline and heavy metal ions than most Ag(+) ISEs reported in the literature.

TL;DR: This work shows that subnanomolar detection limits can also be achieved with SC-ISEs with three-dimensionally ordered macroporous carbon contacts, which have been shown recently to exhibit excellent long-term stabilities and good resistance to the interferences from oxygen and light.
