Patterned adsorption of protein onto a carbohydrate monolayer immobilized on Si
We propose a technique for fabricating a carbohydrate-terminated monolayer (CM) surface, which is extremely flat at the angstrom level. The CM was immobilized onto a Si surface by Si-C covalent bond. Specific adsorption of the protein molecule from a contacting solution was observed on the CM area of a patterned CM substrate surface, while its nonspecific adsorption was observed on the Si-O area.
