Ceramic multi-electrode arrays having platinum recording sites and polyimide insulation produced using precise photolithographic techniques.
Major advantages:
- Robust and reproducible
- Versatile design for rats, mice, non-human primates and other small animal species.
- Biocompatible materials and design features.
- Platform for testing surface modifications: organic layers, enzymes, “nanostructures”.
- Adaptable to “on board” electronics and optical fibers.
- Unique properties of the Pt recording surface provide exceptional catalytic activity.
- Long lasting designs for implantation (days, weeks, months, years?)
A partial list of neurotransmitters and metabolic markers which can be measured in vivo in the CNS using Microelectrode Arrays is shown below:

---|---|
Glucose* | Acetylcholine* |
Lactate* | Choline* |
Glycerol* | Adenosine* |
Pyruvate* | Glutamate* |
ATP* | GABA* |
Oxygen | Dopamine |
Peroxide | Serotonin |
Norepinephrine | |
Nitric Oxide |
