Patterned Electrodes

Patterned gold film fabricated via e-beam metal deposition and photolithography on glass substrate.  Titanium adhesion layer between gold and glass improves mechanical stability of gold film.  Gold films exhibit high purity (99.999%) and low surface roughness (nanometer-scale roughness).  Ideal for applications in MEMS Biosensors (bioMEMS), chemical sensors, biosensors, lab-on-a-chip devices, and field-effect transistors.

Electrodes available in stock include disk electrodes, interdigitated electrodes, four-probe and six-probe electrodes, and electrode arrays.

Features & Benefits
  • Low surface roughness: provides excellent sample-to-sample reproducibility.
  • High-purity gold (99.999%): no need for dangerous/noxious surface cleaning steps.
  • Transparent glass substrate: easily visualize and manipulate your sample.
