  • Title: A Label-free and Highly Sensitive Fluorescence Strategy for Mercury Ion Detection Based on Exonuclease III-aided Recycling Amplification.
    Author: Ding B, Liu C, Wu Q, Wang Y, Li L, Yang H.
    Journal: Anal Sci; 2018; 34(3):259-261. PubMed ID: 29526891.
    Abstract:
    In this paper, we describe a simple and highly sensitive fluorescence strategy of mercury ions based on exonuclease III (Exo III)-aided target recycling amplification to ensure sensitivity. With an ultra high sensitivity (1 pM), our strategy has been simple and cost-effective, which does not need any artificial modification fluorescence groups, and can be carried out in a pot. It also shows excellent selectivity. Therefore, our new method provides an effective platform for mercury-ion detection.
