Abstract
The present invention relates to a logic gate, comprising a metamaterial surface enhanced Raman scattering (MetaSERS) sensor, comprising (a) alphabetical metamaterials in the form of split ring resonators operating in the wavelength range of from 560 to 2200 nm; and (b) a guanine (G) and thymine (T)-rich oligonucleotide that can, upon presence of potassium cations (K+), fold into a G-quadruplex structure, and in presence of Hg2+, form a T-Hg2+-T hairpin complex that inhibits or disrupts the G-quadruplex structure formed in presence of K+, as well as methods of operating and using such a logic gate.
