Abstract

La presente invención divulga un sensor basado en un transistor de efecto de campo (FET) con nanocintas de un material basado en carbono, especialmente grafeno (GNR), una junta semiconductora, electrodos y una compuerta de base compuesta por un material metálico basado en carbono para la detección y medición de bajas concentraciones (nM-pM) de metabolitos (biomarcadores) en organismos vivos. El dispositivo presenta una configuración única de nanocintas de un material basado en carbono, especialmente grafeno (GNR) de tipo brazo de silla (Armchair) en la junta semiconductora y en los electrodos, que favorece la fabricación de arreglos de nanosensores de alta densidad. El dipsositivo presenta ligandos bifuncionales basados en compuestos de pireno enlazados a la junta semiconductora y covalentemente el analito objetivo, generando la estabilidad mecánica, química y electrónica de la señal detectada.
