Polyelectrolyte quenched

PPEs in water and prevent aggregation and self-quenching [53]. Heeger and co-workers paired anionic PPV with a nonconjugated cationic polymer to form a charge-neutral complex and saw both reduction of nonspecific effects and some loss in sensitivity in protein detection [54]. Polyelectrolytes may be best used in assay schemes, such as DNA hybridization assays or drug discovery screens, where the assay conditions are well controlled and nonspecific interactions reduced or avoided. [Pg.365]

The ionic domain of polyelectrolytes also affects the photoinduced charge separation between the coexisting low molecular charged compounds38). The quenching of Ru(bpy)2 + by a zwitterion compound, dibenzylsulphonates viologen (18, BSV), was enhanced about 4 times by poly(vinylsulphate) (PVS)39), and the back reaction... [Pg.20]
