In this paper, we report on the first use of an amperometric fluidic microchip array for the examination of nitric oxide in solution. The array chip is composed of 36 working platinum electrodes on a glass substrate. The electrodes have a diameter of 50 μm ...
An array of electrodes on which cells could be grown directly was fabricated using silicon anisotropic etching and a thick-photoresist process and employed for the detection of nitric oxide (NO) released from a population of adherently growing human umbili ...
Pyroelectric sensor has each pixel's secondary electrode made with no contact with other secondary electrodes. The pyroelectric sensor consists of a series of pixels (12A) with primary (14) and secondary (28) electrodes on opposite surfaces of a thin porou ...
Electrode effects are known for more than 150 years. These effects, with undesirable consequences in industrial aluminium electrolysis, can be used to micro-machine glass with Spark Assisted Chemical Engraving (SACE). In this paper, a novel approach for th ...
Here we present the detection of ultralow concentrations of biomolecules in a device made from a polycarbonate membrane containing a network of gold nanowires and using a “contactless” impedance tomoscopy technique. The sensor comprises a thin dielectric l ...
In their article, ‘‘AC frequency characteristics of coplanar impedance sensors as design parameters’’, Hong et al.1 present an analytical model for the calculation of the resistance between two electrodes in a microchannel. However, their measurements fit ...
The electrochem. oxidn. of EDTA was studied at boron-doped diamond (BDD) electrodes. Cyclic voltammetry in the potential region of water stability showed that EDTA is oxidized in an irreversible 2-electron-transfer mechanism. No fouling phenomena were noti ...
This paper deals with the electrochem. reactivity of B doped diamond (BDD) electrodes. A comparative study was carried out to show the influence of the presence of graphitic micro-domains upon the surface of these films. Those graphitic domains are sometim ...
A device for monitoring the adsorption of target molecules on a substrate, the device comprising a substrate (1), at least a portion of which is formed as a thin dielectric layer. A first, modified surface (2) of the layer has ionizable groups of the subst ...
A conductive composite photoresist has been developed for the direct photopatterning of electrodes. It is based on a dispersion of silver nanoparticles in SU8, a non-conductive, negative-tone photoresist. Manufactured structures have an electrical conducti ...
