Cortical Neurons Grown on Graphene

Biomaterials researchers are constantly looking for substances that can interface with human tissue, such as neurons.  Silicon transistors are one example, but researchers at the Walter Schottky Institute in Munich, Germany have shown that graphene-based bioelectronics have great potential because they are highly conductive and flexible. Graphene forms in sheets of carbon atoms, resembling chicken wire.  The researchers suppose they could be used for implants in ears, eyes and the brain.       MORE
