Seif-assembly of peptide is known to form two-dimensional crystalline structures on the surfaces of two-dimensional nanomaterials. Recently, graphene-based odor sensors exploiting this property have been developed in which peptide solutions are deposited to construct interfaces capable of selectively recognizing odor molecules. Previous studies have predominantly focused on the self-assembly behavior of single peptides, but the structural organization that emerges when multiple peptides are mixed remains largely unexplored. In this study, we deposit mixed solutions of two peptides with markedly different sequences onto hexagonal boron nitride substrates and evaluate the formed structures as a function of peptide concentration.
