Picric acid (PA) detection at parts per trillion (ppt) levels is achieved by a conjugated polyelectrolyte (PMI) in 100% aqueous media and on a solid platform using paper strips and chitosan (CS) films. The unprecedented selectivity is accomplished via combination of ground state charge transfer and resonance energy transfer (RET) facilitated by favorable electrostatic interactions.
通过一种共轭聚电解质（PMI），在100%水性介质中以及在使用纸条和壳聚糖（CS）薄膜的固体平台上，实现了对万亿分之一（ppt）水平苦味酸（PA）的检测。前所未有的选择性是通过基态电荷转移与共振能量转移（RET）相结合来实现的，这种结合由有利的静电相互作用促成。
