Chemo- and biosensors based on fluorescent polyelectrolytes are discussed. The amplified quenching of conjugated polyelectrolytes by oppositely charged quenchers can be used in bioassays to monitor activities of protease, phospholipase A2, and phospholipase C by varying substrates. Enhanced fluorescence yields from cyanine dye J aggregates formed by supramolecular self-assembly between the dyes and polysaccharides can be utilized in assays to monitor glycosidase activity. In addition solution based polyelectrolyte sensors, amplified quenching properties of surface grafted conjugated polyelectrolytes by energy transfer and electron transfer type quenchers are compared.
