Logic gates for multiplexed analysis of Hg2+ and Ag+

Author affiliations

Abstract

The design of devices with multiple functions, simple handling procedures and sufficient sensitivity has drawn great interests in the field of analysis. Metal–nucleotide based pairs, such as T–Hg2+–T and C–Ag+–C complexes accompanied by SYBR Green I (SG), are used to selectively bind duplex-strand DNA by observing a bright fluorescence signal in this work, thus yielding a simple method for the rapid detection of Hg2+ and Ag+ without a complex labeling process. Based on this principle, ‘OR’ and ‘AND’ logic gates for the multiplexed analysis of Hg2+ and Ag+ were developed, and their practical application for the detection of Hg2+ and Ag+ in drinking water was reported.
