A fluorescence assay for the highly sensitive and selective detection of Hg(2+) using a gold nanoparticle (AuNP)-based probe was proposed. The assay was based on the formation of Hg-Au alloys, which accelerated the oxidization of o-phenylenediamine by dissolved oxygen to produce 2,3-diaminophenazine, a fluorescent product.
提出了一种基于金纳米粒子（AuNP）探针的荧光测定法，用于高灵敏度和选择性检测 Hg(2+)。该测定法基于 Hg-Au 合金的形成，该合金加速了邻苯二胺被溶解氧氧化为 2,3-二氨基吩嗪，这是一种荧光产物。
