General description

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency. Find details here.

Application

Platinum black (low bulk density) can be electroplated on implantable microelectrode arrays (MEAs) to improve the impedence of the device. It can be used as a microelectrode for the formation of a microfluidic electrochemical sensor for glucose sensing applications. It can also be used as a photocathode for the production of hydrogen.
