Graphene-coated gold-based SPR interfaces were formed through the transfer of large-area graphene grown by chemical vapor deposition (CVD) on polycrystalline Cu foils. The method allowed successful transfer of single- and double-layered graphene sheets onto the SPR interfaces in a reproducible manner. Functionalization of the graphene interface with mannose was achieved by simple immersion into a mannose aqueous solution (100 mM), resulting in noncovalent interactions between the aromatic ring structure of graphene and mannose. The utility of the carbohydrate-modified graphene-on-gold interface for the selective and sensitive detection of carbohydrate-lectin interactions was demonstrated using model lectins from Lens culinaris (LC) and Triticum vulgaris (TV). While LC lectin binds specifically to mannopyranoside units, TV lectin has an affinity for N-acetyl glucosamine and sialic acid residues.Show less >
