On page 3207, S. H. Choi, D.-H. Kim, and co-workers demonstrate a soft and transparent cell-sheet–graphene hybrid comprising aligned, and differentiated C2C12 myoblasts on buckled, and mesh-patterned graphene electrodes. The hybrid can monitor and/or actuate electrophysiological signals within muscle tissue without immune responses due to the high quality bio-interface formed by the integrated cell sheet. Furthermore, transparency of the hybrid allows simultaneous optical stimulation and recording.
