title: Colorimetric and fluorescent dual detection of paraquat and diquat based on an anionic polythiophene derivative.
abstract: We have developed a colorimetric and fluorescent dual-response probe for the detection of paraquat and diquat in aqueous solutions based on an anionic polythiophene derivative. The detection limit of this approach can be as low as 10(-9) M by fluorescence measurements.
