Two independent groups have demonstrated that nanoscale electrodes can record action potentials in neurons and cardiac muscle cells, and a third group has shown that nanowire field-effect transistors can make electrical measurements on biological materials with unprecedented spatial resolution.

In the News & Views article 'Getting close to the action' originally published online (Nature Nanotech. http://dx.doi.org/10.1038/nnano.2012.22 2012), the signal-to-noise ratio determined by Cui and co-workers was given incorrectly as '∼7'; it should have read 'over 100'. This error has now been corrected in all versions of the News & Views article.'
