Interdigitated Ring Array (IDRA)
Interdigitated Microelectrode Arrays are precision-engineered devices available in either gold or platinum with customizable electrode widths and spacing. They are typically protected with an SU8/PI resin coating, which defines the electrochemical area and enables experiments using extremely small liquid volumes. For research that requires direct electrode exposure, versions without this protective passivation layer can also be supplied. This adaptability gives researchers the freedom to choose the setup that aligns best with their analytical goals.
