Microwire Arrays are designed for both short- and long-term neural recordings in rodent, feline, bird and primate research.
Strengthened Microwire Arrays - SMWA
Their recording reliability stems from a sound construction, which is also highly customizable. Tailoring options include: number of electrodes and rows, length and spacing, insulation and connectors, among others.
The Stainless Steel or Platinum/Iridium wires are individually cut to length and Polyethylene Glycol (PEG) ensures the stable arrangement of the wires while advanced into the target tissue. PEG may be easily washed-off with saline during the insertion process. Such approach allows to researcher for effective deep brain penetration. We offer Polyimide, Borosilicate and Fused Silica capillaries for mechanically strengthening the individual electrodes of the Microwire Array for accessing deeper brain structures.

Microwire Arrays are really made to your specification. They can also incorporate fiber optics and/or drug delivery cannula for precise optogenetic stimulation and local drug administration. It may also be possible to produce these probes beyond the listed parameters to accommodate the most ideal configuration for your research needs.
