Claim 10
Independent Claim
103 words
A method of bonding a chemical species to a metal surface, characterised by the steps of (i) bonding a co-ordinating polymer to a metal surface, the polymer having a first set of functional groups capable of bonding to the surface and having a second set of functional groups capable of bonding to the chemical species, the groups of the first set being pendant from the polymer chain or forming part thereof, the second set being such that the groups thereof do not bond to the metal surface; and (ii) bonding the chemical species to the polymer via the second set of functional groups.
Claim 11
Independent Claim
103 words
A method of bonding a chemical species to a metal surface, characterised by the steps of (i) bonding a co-ordinating polymer to a metal surface, the polymer having a first set of functional groups capable of bonding to the surface and having a second set of functional groups capable of bonding to the chemical species, the groups of the first set being pendant from the polymer chain or forming part thereof, the second set being such that the groups thereof do not bond to the metal surface; and (ii) bonding the chemical species to the polymer via the second set of functional groups.
Claim 12
Dependent Claim
66 words
A method according to claim 9 wherein the coordinating polymer is water-soluble and step (i) is carried out by contacting an aqueous solution thereof with the metal surface, and wherein the chemical species is a biologically active, water-soluble macromolecular substance and step (ii) is carried out by contacting the metal surface to which the polymer has been bonded with an aqueous solution of the chemical species.
