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.
