Injectable electronics treat neurodegenerative disorders

Harvard‘s Charles Lieber has developed a device that can be injected into the brain to treat neurodegenerative disorders and paralysis.

The nanoscale electronic scaffold is injected with a syringe. The scaffolds then connect to devices used to monitor neural activity, stimulate tissues, or  promote neuron regeneration.

In an earlier study, Lieber demonstrated that cardiac or nerve cells grown with embedded scaffolds could be used to create “cyborg” tissue. He was able to record electrical signals generated by the tissue, and  measure changes in those signals as he administered cardio or neuro stimulating drugs.
