Abstract
A rapid, sensitive and selective fluorescence sensor for detection of Pb(2+) was developed based on a Pb(2+)-induced G-quadruplex and graphene oxide. By using a specific G-rich DNA sequence, this strategy provided a promising alternative to Pb(2+) determination in the presence of Hg(2+) escaping from the use of a masking agent of Hg(2+).
摘要
基于 Pb(2+)诱导的 G-四链体和氧化石墨烯，开发了一种用于检测 Pb(2+)的快速、灵敏和选择性荧光传感器。通过使用特定的富含 G 的 DNA 序列，该策略为在存在 Hg(2+)的情况下避免使用 Hg(2+)掩蔽剂来测定 Pb(2+)提供了一种很有前途的替代方法。
