超灵敏检测的信号放大是通过共轭半导体聚合物组件中的能量迁移来实现的。优化这一效应的关键是非聚集聚合物的合成，激发态(激子)的多维定向传输，以及延长共轭聚合物的本征激发态寿命。我们开发了用于生物传感应用的新型水溶性非离子共轭聚合物，可用于提供高灵敏度/特异性的超痕量检测，而不受离子共轭聚合物的特异性问题的影响。
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.
