Disclosed is a method for attaching biomolecules to a solid surface and a composition for preparing that surface for attachment. The composition comprises molecules of Formula I and Formula II which are defined as follows: Y-X-Z-R1 Formula I Y'-X'-Z'-R2 Formula II and wherein R1 is a reactive group which can form a covalent bond with a biomolecule or a group capable of forming a reactive group; R2 is different to R1 and is present in at least a 10<4 >fold molar excess to R1; Y and Y' are groups which can bind to a solid surface; X and X' are atoms which are, at least, bivalent; and Z and Z' are linker groups.
