in this work, designs for planar, interdigitated circular electrode structures for cell membrane permeabilization procedures are analysed using finite element method analysis. The generated electric field intensity, homogeneity and the Joule heating are evaluated. The optimal electrode configuration for successful transfection procedures is investigated. Based on the simulation results, an opti...

This paper presents a label-free affinity-based capacitive biosensor using interdigitated electrodes. Using an optimized process of DNA probe preparation to minimize the effect of contaminants in commercial thiolated DNA probe, the electrode surface was functionalized with the 24-nucleotide DNA probes based on the West Nile virus sequence (Kunjin strain). The biosensor has the ability to detect...

A flexible sensor based on SU-8 photoresist was fabricated and its electrochemical performance was investigated using cyclic voltammetry. The device consisted of interdigitated array (IDA) electrodes on an SU-8 layer. It exhibited a clear electrochemical response during redox cycling of ferrocenemethanol at the IDA electrodes. Since the device was flexible, it could be inserted into a narrow be...

In this work, thin film yttria-stabilized zirconia [YSZ] solid electrolytes were sputtered onto insulating substrates at room temperature and 600oC in order to produce different average grain sizes (~15-50 nm). For reference, polished samples of single crystal and bulk, poly-crystalline YSZ were also used. Platinum film electrodes were then sputtered on top and lithographically patterned to giv...

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...
