Redox Cycling at an Array of Interdigitated Bipolar Electrodes for Enhanced Sensitivity in Biosensing**

Interdigitated coplanar electrodes for enhanced sensitivity in a photorefractive polymer.

Organic photorefractive polymer composites can be made to exhibit near 100% diffraction efficiency and fast writing times, though large external slants are needed to project the applied field onto the grating vector. We show here that the use of interdigitated electrodes on a single plane provides similar performance to these standard devices and geometries but without a external slant angle. T...

Prussian Blue-coated interdigitated array electrodes for possible analytical application

Thin films of iron(W) hexacyanoferrate(I1) (Prussian Blue) were electrochemically deposited on interdigitated array (IDA) electrodes, yielding systems which can be considered as chemiresistors in sensing alkali metal ion concentrations in an adjacent electrolyte. This is due to the fact that the conductivity of the film being measured by a steady-state current on application of a voltage to the...

Development of interdigitated array electrodes with surface-enhanced Raman scattering functionality.

Interdigitated array electrodes with surface-enhanced Raman scattering (SERS) functionality for in situ qualitative and quantitative analysis of electroactive species are demonstrated. Gold nanostructured interdigitated array electrodes (NIDAEs) were fabricated by electron beam lithography, and used for an electrochemical SERS study of K(3)[Fe(CN(6))] in aqueous KClO(4) solution in single and g...

Biosensing at an Individually Addressable Electrochemical Array

AN APPLICATION OF INTERDIGITATED ARRAY OF Pt ELECTRODES FOR ELECTRICAL STIMULATION OF ENGINEERED MUSCLE TISSUE

Electrical field stimulation provides an efficient way to differentiate muscle cells, which results in an increase in the contractile activity and the formation of muscle myofibers. Here, we introduced the use of an interdigitated array of Pt (IDA-Pt) electrodes as a novel platform for the electrical stimulation (ES) of engineered muscle tissues.
