Shenzhen Advanced Institute has developed electrode materials suitable for nerve interface, water oxidation and anti-biological pollution

Recently, the team of Wu Tianzhun, a researcher at the Micro-Nano Center of the Institute of Biomedicine and Health Engineering, Shenzhen Institute of Advanced Technology, Chinese Academy of Sciences, has developed a functional electrode material that is generally suitable for neural interfaces, water oxidation and anti-biological pollution

In recent years, invasive and implantable devices have been widely used in artificial cochlea, artificial retina, deep brain stimulators and other neuroprostheses to treat and diagnose neurological diseases

On the basis of the previous stage, the researchers further developed 3D platinum nanodendrites with a large surface area, and at the same time used a very slow scanning deposition method to better adhere the low content of iridium oxide nanoparticles (<3 wt% Ir) On the platinum nanodendritic structure

In addition, platinum and iridium have excellent catalytic properties and are often used as electrocatalysts for hydrogen evolution reaction (HER) and oxygen evolution reaction (OER)

The above research results effectively solve the existing technical shortcomings, have strong operability, can be mass-produced, and are universally applicable to neural interface, water oxidation, anti-biological pollution, etc.
