First signals from brain nerve cells with ultrathin nanowires
Date:2/20/2013

Electrodes operated into the brain are today used in research and to treat diseases such as Parkinson's. However, their use has been limited by their size. At Lund University in Sweden, researchers have, for the first time, succeeded in implanting an ultrathin nanowire-based electrode and capturing signals from the nerve cells in the brain of a laboratory animal.

The researchers work at Lund University's Neuronano Research Centre in an interdisciplinary collaboration between experts in subjects including neurophysiology, biomaterials, electrical measurements and nanotechnology. Their electrode is composed of a group of nanowires, each of which measures only 200 nanometres (billionths of a metre) in diameter.

Such thin electrodes have previously only been used in experiments with cell cultures.

"Carrying out experiments on a living animal is much more difficult. We are pleased that we have succeeded in developing a functioning nano-electrode, getting it into place and capturing signals from nerve cells", says Professor Jens Schouenborg, who is head of the Neuronano Research Centre.

He sees this as a real breakthrough, but also as only a step on the way. The research group has already worked for several years to develop electrodes that are thin and flexible enough not to disturb the brain tissue, and with material that does not irritate the cells nearby. They now have the first evidence that it is possible to obtain useful nerve signals from nanometre-sized electrodes.

The research will now take a number of directions. The researchers want to try and reduce the size of the base to which the nanowires are attached, improve the connection between the electrode and the electronics that receive the signals from the nerve cells, and experiment with the surface structure of the electrodes to see what produces the best signals without damaging the brain cells.

"In the future, we hope to be able to make electrodes with nanostructured surfac
