Drug Delivery

Combined drug delivery and electrophysiology

The E16-20mm-100-177 electrode array can be mounted on a fluidic tube to combine drug delivery and electrophysiological recording.

The fluidic tube is mounted on the lower side of the microelectrode array, and the delivery port is at the distal end of the fluidic tube. The fluidic interface is compatible with standard HPLC adaptors for interfacing with external injection pumps. Typically, a pressure-based delivery mechanism is used.

As with many of our products, the fluidic probe can be customized. Additionally, the fluidic probe can be augmented with an optical fiber (above image). Contact us for your customization needs.
