A novel electrochemiluminescent immunosensor with polymerization-assisted signal amplification has been developed and enhanced sensitivity was achieved by increasing tertiary amine loading on polymers.

The synthesis of proteinâpolymer bioconjugates is reported using N-succinimidyl ester functionalised polymers from transition metal mediated living radical polymerisation.
An initiator for the terminal group of the polymer product of an atom or gruop radical transfer polymerisation has an activated carboxyl or an amine group which is reacted with an amine or carboxyl (respectively) group containing biologically active compound. The initiator is preferably 4-(3-(2-bromo, 2-methyl-propionate)phenyl)-propionic acid N-hydroxysuccinimide ester or 2-bromo, 2-methyl-propionic acid N-hydroxysuccinimide ester. The monomers preferably comprise a zwitterionic monomer such as 2-methacryloxyethyl-2′-trimethyl ammoniumethyl phosphate inner salt.
The application provides a method of producing a comb polymer comprising the steps of:
(a) Providing:
(i) a plurality of monomers which are linear, branched or star-shaped, substituted or non-substituted, and have an olefinically unsaturated moiety, the olefinically unsaturated moiety being capable of undergoing addition polymerisation;
(ii) an initiator compound; the initiator compound comprising a homolytically cleavable bond.
(iii) a catalyst capable of catalysing the polymerisation of the monomer; and
(b) Causing the catalyst to catalyse, in combination with the initiator, the polymerisation of a plurality of the monomers to produce the comb polymer.
Catalysts and polymers obtainable by the process are also provided.
Preferably, the comb polymer is capable of binding proteins and may be produced from monomers which are alkoxy polyethers, such as poly(alkyleneglycol) or polytetrahydrofuran.
