Electrode Arrays

Drug Delivery

The drug delivery probe includes surface microelectrode array that gets mounted on a fluidic tube to combine drug delivery with electrophysiological recording. The fluid delivery port is at the tip of the probe. These probes are compatible with standard Luer-Lock fittings for interfacing with external injection pumps.

  • Single-insertion: Recordings at the injection site without having to move the cannula
  • Multi-modal: Simultaneous electrophysiology before, during or after drug/fluid delivery
  • Luer lock connection: simple and strong interfacing with syringe pumps
  • Diverse applications: Packaging for acute and chronic use; optogenetics-enabled

D-Series come with attached fluidic channels for drug delivery, and chemical sampling.

  • D16 uses the dual-inline-pin connecter like an acute A16 probe
  • DM16 uses one Omnetics NPD18 connector like a CM16LP probe
  • OD16LP is the acute optoelectrode/drug delivery connector package
  • ODM16LP is the chronic optoelectrode/drug delivery connector package
