Title (EN) METAMATERIAL DEVICE AND USES THEREOF
(FR) DISPOSITIF EN MÉTAMATÉRIAUX ET SES UTILISATIONS
Abstract: front page image
(EN)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.
(FR)La présente invention concerne une porte logique, comprenant un capteur de diffusion Raman à surface améliorée en métamatériaux (MetaSERS), comprenant (a) des métamatériaux alphabétiques sous la forme de résonateurs en anneau fendu fonctionnant dans la plage de longueurs d'ondes de 560 à 2 200 nm; et (b) un oligonucléotide riche en guanine (G) et en thymine (T) qui peut, en présence de cations de potassium (K+), se replier en une structure quadruplex G et, en présence de Hg2+, former un complexe en épingle à cheveux T-Hg2+-T qui inhibe ou détruit la structure quadruplex G formée en présence de K+, ainsi que des procédés d'exploitation et d'utilisation d'une telle porte logique.
