Highly selective and sensitive ratiometric fluorescent polymer dots for detecting hypochlorite in 100% aqueous media

Water-soluble ratiometric fluorescent polymer dots for detecting ClO− (FPDs) were prepared. This nanoprobe features excellent sensitivity (detection limit: 2.2 nM) and selectivity, class water-solubility. In addition, FPDs were successfully utilized to detect ClO− in tap water and drink water.85
