The original reference for Figure 3 is:

R. T. Richardson, B. Thompson, S. Moulton, C. Newbold, M. G. Lum, A. Cameron, R. Kapsa, G. Clark, S. O'Leary and G. G. Wallace, The effect of polypyrrole with incorporated neurotrophin-3 on the promotion of neurite outgrowth from auditory neurons, Biomaterials, 2007, 28, 513–523.

In the second paragraph of the section 'The cellular level' the positions of the reference citations should be adapted as follows:

As early as 1994, studies into the suitability of ICPs such as PPy as neuronal scaffolds demonstrated promising results.^23–25 Shastri et al.²³ showed that neurite extension of PC-12 cells was more pronounced on PPy surfaces compared to tissue culture polystyrene. The authors also showed that the application of an electrical stimulus to the cell culture on the PPy film significantly increased the expression of neurites in the cells compared to the controls. Wallace and co-workers²⁴ used electrical stimulation to provide a release mechanism for a nerve growth factor from the ICP platform.

The Royal Society of Chemistry apologises for these errors and any consequent inconvenience to authors and readers.
