Biocompatibility of polyimide microelectrode array for retinal stimulation

Artificial retina is aimed for the stimulation of remained retinal neurons in the patient with degenerated photoreceptors. Microelectrode arrays have been developed for this as a part of stimulator. To minimize the damage during ophthalmic surgery and to get better contact to retina, flexible polyimide, which can be fabricated based on semiconductor manufacturing, was selected as the substrate ...

Glucose 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...

Nanostructuration strategies to enhance microelectrode array (MEA) performance for neuronal recording and stimulation.

Microelectrode arrays (MEAs) are widely used tools for recording and stimulating extracellular neuronal activity. Major limitations when decreasing electrode size in dense arrays are increased noise level and low charge injection capability. Nanostructuration of the electrode sites on MEAs presents an efficient way to overcome these problems by decreasing the impedance of the electrode/solution...
