Extra-short nanowires best for brain

If in the future electrodes are inserted into the human brain – either for research purposes or to treat diseases – it may be appropriate to give them a ‘coat’ of nanowires that could make them less irritating for the brain tissue. However, the nanowires must not exceed a certain length, according to new research from Neuronano Research Center at Lund University in Sweden.

This is the conclusion from an experiment in which the long-term effects of nanowires of different sizes were tested. The nanowires were mixed into a saline solution that was injected into the brains of lab animals, and the results were compared with an injection of saline alone.
