title: Highly sensitive naked-eye and fluorescence "turn-on" detection of Cu(2+) using Fenton reaction assisted signal amplification.
abstract: Increase of pH induced by Cu(2+)-catalyzed Fenton reaction promoted ring-opening of triazole-linked fluorescein lactone, which enabled selective "turn-on" fluorescent detection of Cu(2+), along with ultralow naked-eye detection limit down to 200 nM.
