Patent ID: 7297553

Claim:
A method for immobilizing a molecule onto a surface, said method comprising the steps of: (a) contacting Si(NCY) 4 with an agent having a formula ii: (R 1 )(R 2 )(R 3 )Si—X-Z ii so as to form a first reactive intermediate, wherein Y represents oxygen or sulphur, R 1 , R 2 and R 3 independently represents C 1 -C 6 alkoxy, C 1 -C 6 alkyl, phenyl, or aryl substituted with one or more groups selected from the group consisting of C 1 -C 6 alkyl and C 1 -C 6 alkoxy; X represents linear or branched C 1 -C 20 alkyl or aryl substituted with one or more groups selected from the group consisting of C 1 -C 6 alkyl and C 1 -C 6 alkoxy, optionally substituted with one or more heteroatoms comprising oxygen, nitrogen, or sulfur; and Z represents a hydroxy or amino group, with the proviso that at least one of R 1 , R 2 or R 3 represents C 1 -C 6 alkoxy; (b) contacting the first reactive intermediate with a molecule so as to form a second reactive intermediate; (c) contacting the second reactive Intermediate with said surface so as to immobilized the molecule onto said surface.
