Protein-based proton-conducting materials have received considerably less attention than other, man-made materials, despite offering greater potential for modularity, tunability and processability.
Proton-conducting materials are essential for renewable energy and bioelectronics technologies. Many modern devices rely on the transport of protons, ranging from fuel cells and transistors to biosensors and medical implants. Protein-based proton-conducting materials have received considerably less attention than other, man-made materials, despite offering greater potential for modularity, tunability and processability.
