Title: | Intelligent and ultrasensitive analysis of mercury trace contaminants via plasmonic metamaterial-based surface-enhanced Raman spectroscopy | Authors: | Cao, Cuong Zhang, Jun Li, Shuzhou Xiong, Qihua |
Keywords: | DRNTU::Science::Physics | Issue Date: | 2014 | Source: | Cao, C., Zhang, J., Li, S., & Xiong, Q. (2014). Intelligent and Ultrasensitive Analysis of Mercury Trace Contaminants via Plasmonic Metamaterial-Based Surface-Enhanced Raman Spectroscopy. Small, 10(16), 3252-3256. | Series/Report no.: | Small | Abstract: | Label-free molecular logic gates (AND, INHIBIT, and OR) are constructed based on specific conformation modulation of a guanine- and thymine-rich DNA, while the optical readout is enabled by the tunable metamaterials which serve as a substrate for surface enhanced Raman spectroscopy. The DNA logic is simple to operate, highly reproducible, and can be stimulated by ultra-low concentration of the external inputs, enabling an extremely sensitive detection of mercury ions down to 2 × 10−4 ppb. | URI: | https://hdl.handle.net/10356/99464 http://hdl.handle.net/10220/19638 |
