Opis ogólny

Iridium oxide is a ceramic material with unique properties like long-term stability, sensitivity, electrochemical catalytic activity, and excellent biocompatibility. It can be formed from Ir metal by different methods like thermal decomposition, reactive sputtering, and electrochemical deposition. It is widely used in bio-electronic devices.

Zastosowanie

Iridium(IV) oxide can be used as:
  • An indicator electrode in solid-state pH sensors.
  • Coating material for stimulation electrodes.
  • An anodic catalyst for oxygen evolution through a water-splitting reaction in a polymer electrolyte membrane (PEM) cell.

Release of neurotransmitters and hormones by calcium regulated exocytosis is a fundamental cellular/molecular process that is disrupted in a variety of psychiatric, neurological, and endocrine disorders. Therefore, this area represents a relevant target for drug and therapeutic development, efforts that

A facile, in-situ deposition route to stable iridium oxide (IrO(x)·nH(2)O) nanoparticle thin films from [Ir(OH)(6)](2-) solutions is reported. The [Ir(OH)(6)](2-) solution, made by alkaline hydrolysis of [IrCl(6)](2-), is colorless and stable near neutral pH, and forms blue IrO(x)·nH(2)O nanoparticle suspensions
