Nanostructured materials have been explored as critical components to design highly sensitive and selective supramolecular electrochemical sensors. The performance improvement of these sensors is often attributed to the large surface area and the controlled permeability of the nanostructures for ions and molecules. In addition, their nanospaces can afford unique environments...

The techniques of confocal Raman microscopy and neutron reflectometry are being adapted as non-destructive probes of interfaces within ion conductive membranes that have application as anode/cathode separators in fuel cells and devices for solar-fuels production. In the study of ionomer-graphene composites, the ability to measure within membranes formed by sandwiching...

Understanding the behavior of chemical reactions in confined volumes is important in applications ranging from water purification to healthcare devices. Especially relevant are wetting and dewetting phenomena which can be switched by external stimuli, such as light, electric fields, and the presence of chemical modulators, such as H+. These behaviors...

The charge storage and membrane applications of graphene oxide materials are dictated by its intrinsic material proper-ties. Structure-function relationships correlating periodic parameters, such as hydrated ion radius and ion-graphene oxide interactions, are currently lacking yet needed to provide insight on the charge storage and ion transport mechanism. We will discuss...

We describe measurements with Scanning Ion Conductance Microscopy geared toward quantitative analytical measurements at biological interfaces. Use of nanoscale pipettes that interact in a noncontact fashion with interfaces of interest. We show application to cell monolayers and use of ion channels as sensors, as well as carbon electrodes used for...
