Highly sensitive biological and chemical sensors based on reversible fluorescence quenching in a conjugated polymer
The fluorescence of a polyanionic conjugated polymer can be quenched by extremely low concentrations of cationic electron acceptors in aqueous solutions. We report a greater than million-fold amplification of the sensitivity to fluorescence quenching compared with corresponding “molecular excited st...
