Graphene-based probes developed to aid brain scanning processes

30th March 2017

Researchers have developed flexible new neural probes using graphene that could represent a step forward in carrying out brain scans.

Developed by collaborators on the EU-wide Graphene Flagship project, the probes allow brain activity to be measured at high resolutions while maintaining an excellent signal-to-noise ratio. They are also non-toxic and do not cause inflammation.

The devices have been successfully used to record the large signals generated by pre-epileptic activity in rats, as well as the more subtle levels of brain activity recorded during sleep and in response to visual light stimulation.

Brain implants such as these can also be used as neural prostheses for therapeutic brain stimulation technologies and interfaces for sensory and motor devices, such as artificial limbs.

Study leader Jose Antonio Garrido of the Catalan Institute of Nanoscience and Nanotechnology said: "Graphene neural interfaces have shown already great potential, but we have to improve on the yield and homogeneity of the device production in order to advance towards a real technology."

Graphene is considered to be one of the most versatile and promising materials ever developed,  thanks to its immense strength, flexibility, conductivity and thinness.
