Investigation of microelectrodes
Journal of Electroanalytical Chemistry, 1992Abstract Microband electrodes display a very strong edge effect. The diffusion layer at a microband electrode may be considered as a semicylinder. When a microband-array electrode is electrolysed for a long time, these diffusion layers partially overlap each other and the total current is smaller than the sum of the currents at all single-microband ...

Diffusion-limited chronoamperometry at conical-tip microelectrodes
Electrochimica Acta, 2010 In this paper, we present simulated diffusion-limited time-variant currents at conical-tip microelectrodes fabricated by depositing a carbon film in and on pulled quartz capillaries.

Heat generation at disk microelectrodes by a high-amplitude (few volt) and high-frequency (0.1-2 GHz) alternating voltage is described. This method allows changing electrode temperature very rapidly and maintaining it well above the boiling point of solution for a very long time without any indication of boiling. The size of the hot zone in solution is

Abstract The chief applications of microelectrodes in medicine are in experimental studies of tissue and cell behaviour and of metabolism. Microprobes have been developed for a wide range of specific substrates and for the detection of bioelectric potentials.

Magnetically gated microelectrodes
Chem. Commun., 2012Microelectrodes fabricated in the center of single-coil microelectromagnetic traps are described. Magnetic particles are then used to reversibly gate transport of an electroactive species to the surface of the electrode or as a means to produce an ON/OFF bioelectrocatalytic glucose sensor.

Studies on Electroosmotic Effects in Glass Microelectrodes - Improvement of Microelectrode Selection
IEEE Transactions on Biomedical Engineering, 1984Changes in the resistance and tip potential of open-tip glass microelectrodes as function of the polarity and intensity of an injected current are presented and analyzed. These experimental results are explained on the basis of a quantitative diffusion model which includes an electroosmotic effect through the microtip.

Journal of Neuroscience Methods, 1979
A technique for making recording microelectrodes containing an ultrafine carbon fibre is described. This technique can be used for single- and multi-barrel microelectrodes. These microelectrodes not only have a very low signal-to-noise ratio comparable with that found in tungsten microelectrodes but are simpler to make.

An improved pCO2 microelectrode
Analytical Biochemistry, 1978Abstract By utilizing the recently developed glass-membrane pH microelectrode an improved pCO 2 microelectrode has been manufactured. The new pCO 2 microelectrode described here has been made with tip diameters ranging from 2 to 200 μm. In addition, the sensitivity (slope) was nearly theoretical, 56 to 60 mV/log pCO 2 , the response time was 1–3 ...

Measurement of glass microelectrodes
Experientia, 1964Zur Untersuchung der elektrischen Zellmembraneigenschaften sind bekanntlich besonders scharfe Glaselektroden Voraussetzung. Mit Hilfe eines modifizierten Elektronenmikroskops kann sowohl Wandbreite, wie auch innerer Durchmesser der Mikroelektrodenspitze gemessen werden.
