| مستخلص: |
Glass conical nanopores functionalized with a macrocyclic dioxotetraamine derivative (C5) are shown to enable ultrasensitive determination of Hg(II). A complex is formed between Hg(II) and C5, and this converts the functionalized glass nanopore from a rectifying state to a non-rectifying state. The presence of Hg(II) in ~10 pM levels or higher can be detected by measuring the ion current rectification ratio in voltage range of ± 500 mV. This sensing strategy opens new possibilities for development of a simple, portable and convenient device for the quantitation of Hg(II) with very low limits of detection.
