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.

Analytical Chemistry, 2002
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

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 ...

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.

Pipette-integrated microelectrodes
Nature Biomedical Engineering, 2019A suite of microelectrodes integrated into glass pipettes, for the simultaneous recording of intracellular and extracellular data in the brains of living mice and rats, yields ground-truth data for the validation of the performance of spike-sorting algorithms.

Nitrite-selective microelectrodes
Talanta, 1994The development of nitrite-selective liquid membrane microelectrodes based on a synthetic charged ionophore is described. The addition of potassium tetrakis(4-chlorophenyl)borate and poly(vinyl chloride) to the membrane phase is essential to lower the ohmic resistance and to prolong the lifetime of the microelectrodes.

Philosophical Transactions of the Royal Society of London. B, Biological Sciences, 1987
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.

Another tungsten microelectrode
Medical & Biological Engineering, 1972A technique is described for fitting a sharpened tungsten wire and a glass micropipette together so that a precisely controlled amount of bare wire is exposed at the tip. The method is tedious and demanding but produces very reliable electrodes yielding isolated extracellular recordings from single nerve cells and their axons.

Ca2+-selective microelectrodes
Cell Calcium, 1985Ca2+-selective microelectrodes based on the synthetic neutral carrier ETH 1001 can be used for quantitative intracellular measurements of resting Ca2+-activities and of slowly changing Ca2+-levels (response time in the order of seconds). Microelectrodes with tip diameters greater than 0.3 micron show selectivities that yield a detection limit between ...
