Neurosurgeons get ready to bring graphene to the operating table
By John Hewitt on May 1, 2014
With graphene you can pretty much name your favorite physics phenomenon, and there will be some way that the material can be used to exploit it. Graphene is so thin that it’s transparent — but also, per gram, one of the most light-sensitive materials in the world. Unlike many other metamaterials, it is also a good absorber in the IR and UV ranges. What excites some neurosurgeons is that past a certain threshold of illumination, graphenedisplays what is called “saturable absorption” — beyond this illumination point ,graphene releases extra energy in the form of heat which can potentially be harnessed to kill tumors.
