On microelectrode ionophoresis.
An equation for ionophoresis in large tip microelectrodes is derived from Nernst-Planck equations for the general case of a completely dissociated electrolyte. The relation between the release of ions and the applied electric current is mainly determined by two parameters: the transference number of the ions under consideration and the diffusional leak of the microelectrode. Also it is shown ho...
متن کاملGlucose sensing based on interdigitated array microelectrode.
A micro glucose sensor consisting of an interdigitated array gold microelectrode was developed. The interdigitated array structure, which has 10 microns band width and 10 microns band gap, was fabricated in a small region (2.5 x 5 mm2) on a quartz substrate. Glucose oxidase was chemically fixed onto the electrode surface through self-assembled monolayer of 11-mercaptoundecanoic acid; ferrocenea...
متن کاملMicroelectrode Arrays
The development of implantable devices which enable fully wireless transmission of brain signals, recorded by microelectrode arrays (MEA) as dynamical neural circuit information, is one important goal for advancing human neuroprostheses. Current brain sensing research for prostheses via first clinical trials is offering tantalizing glimpses for the future, even if these technologies are cumbers...
متن کاملSeparation and determination of ribonucleotides and related compounds by ionophoresis on filter paper.
The metabolic turnover of the nucleic acids and their constituent parts has been a subject of increasing significance during recent years. Such studies have been facilitated in this laboratory by the use of ionophoresis on filter paper. The usefulness of this technique is accentuated by the fact that very small amounts of material may be used, that actual physical separation is achieved, and th...
متن کاملChapter 16 Microelectrode electronics
These notes are intended to provide an introduction to the electronics of microelectrode and patch clamp amplifiers. How much electronics do you need to use a physiological amplifier? Enough to know how much distortion is introduced by the measurement. This means (1) testing the response to an input that simulates the physiological signal, (2) calibrating the gain and frequency response, and (3...
