研制了一种基于氧化石墨烯（GO）集成的Hg（II）纳米梯的生物传感器，用于Hg（II）的检测。纳米梯子本质上是由T-Hg（II）-T支撑的DNA三明治结构，用于Hg（II）捕获和信号翻译。GO用于区分由Hg（II）纳米梯子产生的荧光与背景信号。
A biosensor based on Hg(II) nanoladders integrated with graphene oxide (GO) for Hg(II) detection was developed. Nanoladders were essentially DNA sandwich structures supported by T-Hg(II)-T and were used for Hg(II) trapping and signal translation. GO was used to differentiate the fluorescence generated by Hg(II) nanoladders from a background signal.
