Abstract

In this paper, a simple strategy for the sensitive detection of hydroquinone (H2Q) using fluorescent silver nanoclusters (AgNCs) has been developed. In the presence of H2O2 and peroxidase, the fluorescence of AgNCs was quenched efficiently by phenolic compounds. The mechanism inherent in the fluorescence quenching could be mainly ascribed to the formation of the quinone intermediates via enzyme-catalyzed oxidation of phenolic compounds. Combined with the high specificity of the enzyme, the method could determine phenolic compounds with a linear relationship ranging from 8.0 × 10−8 to 3.2 × 10−6 mol L−1 and a detection limit of 10−8 mol L−1. In the case of phenols, the presented sensor may serve as a comparative empirical method for the evaluation of contamination.
