Signal amplification for ultra‐sensitive detection has been achieved by energy migration in conjugated semiconducting polymeric assemblies. Critical to optimizing this effect is the synthesis of non‐aggregate polymers, the multidimensional directional transport of excited states (excitons), and extending the intrinsic excited state lifetime of conjugated polymers. We developed new water‐soluble non‐ionic conjugated polymers for use in biosensory applications, which can be used to provide highly sensitive/specific ultra‐trace detection that is immune to specificity problems that plauge ionic conjugated polymers.
