Contamination of the environment with toxic Hg(II) is becoming a huge concern throughout the world now. Driven by the need, this communication reports for the first time a tryptophan protected popcorn shaped gold nanomaterials based SERS probe for rapid, easy and highly selective recognition of Hg(II) ions in the 5 ppb level from aqueous solution, with high sensitivity and selectivity over competing analytes. We demonstrate that our SERS assay is capable of measuring the amount of Hg(II) in alkaline battery.
目前，环境中有毒的 Hg(II) 污染已经成为全世界关注的焦点。受此需求的推动，本通讯首次报道了一种色氨酸保护的爆米花状金纳米材料基于 SERS 探针，用于快速、简便、高选择性地识别水溶液中 5 ppb 水平的 Hg(II) 离子，对竞争分析物具有高灵敏度和选择性。我们证明了我们的 SERS 分析能够测量碱性电池中 Hg(II) 的含量。
