Herein, we demonstrate the first use of a reduced graphene oxide (rGO)-organic dye nanoswitch for the label-free, sensitive and selective detection of Hg(2+) using bifunctional rGO as an effective nanoquencher and highly selective nanosorbent. Moreover, a reversible on-off INHIBIT rGO logic gate based on a cysteine-Hg(2+) system has also been designed.
在这里，我们展示了还原氧化石墨烯 (rGO)-有机染料纳米开关在无标记、灵敏和选择性检测 Hg(2+)方面的首次应用，使用双功能 rGO 作为有效的纳米猝灭剂和高选择性纳米吸附剂。此外，还设计了基于半胱氨酸-Hg(2+)体系的可逆 ON-OFF rGO 逻辑门。
