Cover: Conductive hydrogels are softer, more mechanically robust materials for tissue interfacing devices where conductivity is desirable. The biologically active, anionic hydrogel component effectively and stably dopes the conducting polymer component to form an electroactive material which supports neural cell survival and growth. Further details can be found in the article by R. A. Green,* R. T. Hassarati, J. A. Goding, S. Baek, N. H. Lovell, P. J. Martens, and L. A. Poole-Warren on page 494.
