Patent ID: 8778846

Claim:
A composition, comprising: a first probe; a first initiator component bonded to the first probe; a second probe chemically distinct from the first probe; a second initiator component bonded to the second probe, wherein the first probe and the second probe are bonded to a single analyte such that the first initiator component and the second initiator component form an initiator, with the proviso that the first initiator component and the second initiator component are independently inactive when the first probe and the second probe are not bonded to the analyte, wherein the initiator is present between the polymer and each of the first probe and the second probe; and a polymer bonded to the initiator, wherein the polymer is bonded to a plurality of signal generators, wherein the polymer comprises structural units derived from a polymer precursor comprising an atom transfer radical polymerization (ATRP) monomer, a ring opening metathesis polymerization (ROMP) monomer, or combinations thereof.
