Application of Platinum Nanoparticle in Graphene Electrodes

Using platinum nanoparticle, graphene electrode impedance could be lower by 100times and transparent. The lower impedance graphene electrodes were able to record an image neuronal activity, such as Calcium ion spikes, at both macro cell and single cell levels. Graphene electrodes enable higher quality imaging of brain cell activity. Recently graphene electrode is a step closer to being adapted into next-generation brain imaging technologies and various basic neuroscience and medical applications.

Researchers have been exploring graphene electrodes for use in neural implants. They have several advantages over the traditional metal electrodes. They are flexible So they can confirm better to brain tissue. Also, they are transparent, which makes them possible to both record and see the activities of neurons directly beneath the electrodes that would otherwise be blocked by opaque metal materials.

Graphene electrodes are under high impedance, This hampers communication between the brain and the recording devices. The noisy reading comes as a result. The transparency of metal will be ruined if researchers try various techniques to reduce the impedance of the graphene, researchers have developed a technique to engineer graphene electrodes those are both 100times lower in impedance and transparent.
