Materials that can interface biological signaling with conventional technologies are crucial for the realization of new therapeutic and sensing platforms based on direct readout and responses to biological signals. However, one great challenge is lack of biocompatible ion and proton conducting materials that exhibit anisotropic properties at biologically relevant length-scales, nano to micro, and relevant time scales, miliseconds to seconds. In this talk I will present our work on the repeat-protein biomaterials that self-assemble through the combination of head-to-tail stacking and weak dipole-dipole interactions. I will further highlight the effect that this hierarchical structure has on the material’s mechanical and proton and ion conduction properties.
