Carbon fibre microelectrodes

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, 2019
A 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, 1994
The 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.

Microelectrode

2021
The present invention relates to a microelectrode, in particular a microelectrode for Scanning Electrochemical Microscopy and electroanalysis or for microchemical reactrors and for so-called electrochemical micromachining (EMM), and to a manufacturing method thereof.

Microelectrodes in medicine

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, 1972
A 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, 1985
Ca2+-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 ...

Intracellular Oxygen Microelectrodes

1973
In this presentation the work of many associates of mine will be discussed, most notably Dr. Pankajam Nair. I will say little about the construction of the micro O2 electrode since the method is essentially the same as has been published (7). Rather, I will first briefly discuss tests of its reliability and new calibration techniques; then some of our ...

Extracellular microelectrode sampling bias

Experimental Neurology, 1970
Abstract The antidromic response latencies of 640 pyramidal tract neurons, isolated in pericruciate cortex of the cat, were measured after stimulation of the medullary pyramids. The expected time distribution of antidromic response latencies was then calculated from published values for axon diameters in silver-stained preparations; compensation for ...

Glass Insulated Platinum Microelectrode

Science, 1960
Microelectrodes for electrophysiological use have been prepared easily and quickly by electrolytically sharpening platinum iridium alloy wire and coating with molten glass. The desirable combination of the electrical characteristics and strength of the platinum iridium wire with the exceptional durability of glass insulation has long been known, but ...
