[EN] We demonstrate a redox-sensitive nanofluidic diode whose ion rectification is modulated by the oxidation and reduction of chemical moieties incorporated on its surface. To achieve this goal, we have first synthesized ...
[EN] We demonstrate experimentally and theoretically a nanofluidic
device for the selective recognition of the cesium ion by exploiting
host¿guest interactions inside confined geometry. For this purpose, a host
molecule, ...

We describe the fabrication of a chemical-sensitive nanofluidic device based on asymmetric nanopores whose transport characteristics can be modulated upon exposure to hydrogen peroxide (H2O2). We show experimentally and ...
[EN] The label¿free detection of pyrophosphate (PPi) anions with a nanofluidic sensing device based on asymmetric nanopores is demonstrated. The pore surface is functionalized with zinc complexes based on two di(2¿picolyl)amine ...
[EN] The lithium ion recognition is receiving significant attention because of its application in pharmaceuticals, lubricants and, especially, in energy technology. We present a nanofluidic device for specific lithium ion ...

We describe the fabrication of asymmetric nanopores sensitive to ultraviolet (UV) light, and give
a detailed account of the divalent ionic transport through these pores using a theoretical model
based on the Nernst-Planck ...
4-oxo-4-(pyren-4-ylmethoxy) butanoic acid is used as a photolabile protecting group to show the optical gating of nanofluidic devices based on synthetic ion channels. The inner surface of the channels is decorated with ...
