Application

Platinum black (black, powder, ≤20 μm) can be electroplated on implantable microelectrode arrays (MEAs) to improve the impedence of the device. It can also be used as a microelectrode for the formation of a microfluidic electrochemical sensor for glucose sensing applications. It can be used as a photocathode for the production of hydrogen.
Platinum black can be used as a catalyst to facilitate the electrochemical reactions in proton exchange membrane (PEM) fuel cells. These fuel cells are promising candidates as a clean and energy efficient power source.

We recently reported that peritumoral CpG-ODN treatment, activating TLR-9 expressing cells in tumor microenvironment, induces modulation of genes involved in DNA repair and sensitizes cancer cells to DNA-damaging cisplatin treatment. Here, we investigated whether this treatment induces modulation of miRNAs
