[‚mī·krō·i′lek‚trōd]
(engineering)
In biological research, an electrode with a microscopic tip dimension that may be placed adjacent to or inside a cell for the purpose of recording the electric potentials of single cells, passing electrical currents, or injecting electrically charged substances into the cell.
In physical chemistry, a minute electrode used to perform electrolysis of small quantities of material.

Each of these graphene forms can be explored to produce novel microelectrodes that interface with electrogenic neurons, and there is potential to combine the different forms with each other or with other materials in order to enhance or take advantage of a particular characteristic.
Also, the aromatic group of dopamine undergoes favorable [pi]-[pi] interactions with the [sp.sup.2] hybridized CNTs, which further facilitates adsorption to the surface of the carbon nanotube fiber microelectrode. The higher porosity of the CNT fibers also provided further sites for analyte adsorption.
This indicates acceptable cyclability of PCW/CMP microelectrodes compared to electrochemical microcapacitors reported by Cui et al., where 62.9% of the initial capacitance is retained after 2000 cycles [21].
Ultrahigh resolution, in the zeptoFarad ([10.sup.-21] F) range, is only achievable with a monolithic combination of the microelectrodes with the ASIC implementing the readout circuits [12, 13].

To confirm their hypothesis, they inserted hair-thin microelectrodes into the dentate gyrus of rats -- an area within the hippocampus which is responsible for memories of space and location -- allowing them to send weak electrical impulses to individual granule cells.
The intracellular action potentials were obtained using glass microelectrodes filled with 3M KCl solution and with a tip resistance of between 10 and 20 megaohms.
By using two of these microelectrode arrays, the Pittsburgh team has demonstrated the ability to control seven degree-of-freedom movements of a robotic arm (three-dimensional movement of the arm in space, three-dimensional rotation of the wrist and the opening or closing of the hand for grasping).
After identifying the STN by microelectrode recording (MER), the DBS electrodes were implanted and connected to an implanted programmable generator.
