nature. This complexity had been made it hard to study about carbohydrate related researches. In the present work, we report a simple and rapid modification technique for constucting carbohydrate chip platform onto a glass surface is accomplished by coupling the amine group of another group-bearing linker as a new coupling reagent with an aldehyde group of the terminal reducing sugar in the carbohydrate. Modified carbohydrate containing functional amine group immobilized onto NHS-ester surface. To demonstrate the generality of this proposed reductive amination method, we examined HPLC, MALDI-TOF, and NMR analysis for lactose and maltose (disaccharide). Through successful identifications of the modified carbohydrates and direct binding assays using terminal saccharide-binding lectin and GM1-ctxB binding assays, we confirmed several advantages including direct and rapid one-step immobilization onto glass surface and exposure of functional carbohydrate moieties through oriented modification of the terminal reducing sugar. Therefore, this facile modification and immobilization method can be successfully used for diverse biomimetic studies of carbohydrates, including carbohydrate-biomolecule interactions and carbohydrate sensor or array development for diagnosis and screening.
