Design of a dual-output fluorescent DNA logic gate and detection of silver ions and cysteine based on graphene oxide

Abstract

In the presence of graphene oxide, upon formation of cytosine–Ag–cytosine the fluorescence wavelength of FAM-labeled DNA exhibited a red shift, and its intensity significantly increased. A novel fluorescent DNA sensor for Ag+ and cysteine detection, and a dual-output fluorescent DNA INHIBIT logic gate are designed.
