Abstract
Silicon Carbide is a promising material to overtake the limitations of Si sensors used for in vivo detection. Here, two different nanodevices are presented. The first one is a SiC NWFET used for electrical detection of DNA molecules. The addition of DNA probe molecules increases the current by 25% and the hybridization with DNA targets increases by 80%. This confirms the efficiency of our sensor to detect DNA. The second one is a Metal Insulator Semicondutor capacitor composed of DNA functionalized SiC nanopillar arrays embedded in a sol-gel silicon dioxide matrix. Capacitance measurements show a singular response between 80 and 100 Hz which is attributed to the presence of DNA molecules.
