one in the eye

Graphene; remarkable stuff, with remarkable amounts of money now being spent on it. Use graphene as a transistor material instead of something like silicon and you can get an electrical component able to exploit the body’s own electrochemistry in its operation. I spoke to a group in Germany which thinks it can turn that particular behaviour to good use in retinal implants, where better sensitivity and less general complexity would be a fine idea. Plus there should be other in-body uses too; the EU’s Graphene Flagship program has started to consider biomedical applications, and you can buy a lot of progress for one billion Euros.
