Organic electronics sounds more like something from a new sci-fi thriller than from lab research, but a team of chemists at Johns Hopkins University has created water-soluble electronic wires made from carbon-based compounds –- rather than metal. This means that the wires could be used inside the human body, in pacemakers or to stimulate damaged nerves. The materials are soft, lightweight, and assemble themselves into wires finer than a human hair. Using these little fibers inside the human body is still some time off in the future, but they may be able to conduct electricity at the cell level –- meaning doctors could re-engineer neural networks for people who have lost them.
