This manuscript reports on the direct identification of four states of water in hydrated Nafion ionomer polymers, including a quantitative measurement of their dynamics, as previously published in the Journal of the Electrochemical Society, 155, B163-B171 (2008). Here, we provide further details on the dynamics of these water states and we underline still-open scientific questions, towards stim...

Since the early 70s electrochemistry has been used as a powerful analytical technique for monitoring electroactive species in living organisms. In particular, after extremely rapid evolution of new micro and nanotechnology it has been established as an invaluable technique ranging from experiments in vivo to measurement of exocytosis during communication between cells under in vitro conditions....

Some conventional machining methods have been developed to machine microelectrodes. However, these methods still require too much time and too many resources. This paper uses electrochemical etching as an alternative method for the simple and cheap fabrication of microelectrodes. Electrochemical etching is usually considered an appropriate method of producing sharp probes. However, it is possib...

This paper presents a new design and fabrication process of a multiple-thickness electrochemical cantilever sensor, in order to assess the role of the cantilever’s thickness on the chemically-induced mechanical effects. Each cantilever can act not only as a functionalized cantilever, but also as an independent working electrode (WE) for electrochemical measurement. The different thicknesses of ...

A nanostructured film electrode, a multi-wall carbon nanotubes (MWNT)-modified glassy carbon electrode (GCE), is described for the simultaneous determination of guanine and adenine. The properties of the MWNT-modified GCE were investigated by scanning electron microscopy (SEM) and cyclic voltammetry. The oxidation peak currents of guanine and adenine increased significantly at the MWNT-modified...
