Single-molecule-high sheets of graphene oxide mix in solution with synthetic tandem-repeat proteins patterned on squid ring teeth. The two separate materials self-assemble so that the tandem-repeat protein attach to the edges of the graphene oxide sheets — one end on a sheet — to bring the graphene into stacks and uniformly space the sheets. The amount of spacing between graphene oxide sheets is determined by the length of the tandem repeat protein.
