The present invention provides a silane molecule which combines pre-activated and protein-resistant functionalities in one molecule; the molecule has a general formula:
A-(CH
2
)
n
—(O[CH
2
]
t
)
m
—(CH
2
)
v
—Y (1)
wherein A is a functional group for binding to a substrate and Y is a functional group for binding to biomolecules. The invention furthermore provides a method for the synthesis of such a silane molecule and a method for depositing a monolayer of such silane molecules onto a substrate. Such a monolayer of silane molecules may be used in biosensors, DNA/protein micro-arrays or other sensor applications. For further lowering the protein binding to the surface of the biosensor, the monolayer may furthermore comprise second silane molecules with formula:
B—(CH
