Examples of Cyclic Voltammograms

Activated Iridium Oxide (AIROF)

CV in Phosphate Buffered Saline (PBS) at a sweep rate of 50 mV/s. Argon has been bubbled through the PBS to remove dissolved oxygen gas.

Sputtered Iridium Oxide (SIROF)

CV in Phosphate Buffered Saline (PBS) at a sweep rate of 50 mV/s. Argon has been bubbled through the PBS to remove dissolved oxygen gas.

Electrodeposited Iridium Oxide (EIROF)

image006

CV in Phosphate Buffered Saline (PBS) at a sweep rate of 50 mV/s. Argon has been bubbled through the PBS to remove dissolved oxygen gas.

Titanium Nitride (TiN)

ass

CV of high-surface-area, fractal titanium nitride in Phosphate Buffered Saline (PBS) at a sweep rate of 50 mV/s. Argon has been bubbled through the PBS to remove dissolved oxygen gas.

The CV is indicative of capacitive charge transfer by charging and discharging the TiN-electrolyte double-layer.  There is evidence of faradaic processes (reduction and oxidation) at the electrode.

Platinum (oxygen reduction)

as

The effect of oxygen reduction on a platinum electrode is shown by cyclic voltammetry in PBS at a sweep rate of 50 mV/s.

Limitations: The use of test results and test articles for any application is the sole responsibility of the end-user. Results of in vitro testing do not establish in vivo safety. The performance of electrodes and electrode devices and the robustness of encapsulation may depend on the manner of use, post-fabrication history, and other factors that are not predictable.
