基于一种新的荧光碱基T-diox，设计了一种高选择性、高灵敏度的汞离子传感器。利用错配的T-diox-T和T-diox-C碱基配对研究了其金属传感能力。该传感器具有较高的灵敏度（猝灭效率，80%，1：1结合模式）和选择性时，加入汞离子。
A highly selective and sensitive sensor for mercury was designed based on a new fluorescent nucleobase, T-diox. Its metal-sensing ability was investigated using mismatched T-diox-T and T-diox-C base pairing. The sensor exhibited a high sensitivity (quenching efficiency, 80%, 1 : 1 binding mode) and selectivity upon the addition of mercury ions.
