摘要： A solid state molecular sensor having an aperture extending through a thickness of a sensing region is configured with a sensing region thickness that corresponds to the characteristic extent of at least a component of a molecular species to be translocated through the aperture. A change in an electrical characteristic of the sensing region is measured during the molecular species translocation. The sensor can be configured as a field effect transistor molecular sensor. The sensing region can be a region of graphene including an aperture extending through a thickness of the graphene.

摘要： A method of generating a metamater-operable in the visible-infrared range is provided. The method comprises a) depositing a layer of a conductive material on a substrate; b) forming a layer of electron beam resist on the layer of conductive material; c) patterning the layer of electron beam resist using electron beam lithography to form a patterned substrate; d) depositing a layer of a noble metal on the patterned substrate; and e) removing the resist. A metamaterial operable in the visible-infrared range comprising split-ring resonators having a least line width of about 20 nm to about 40 nm on a substrate is provided. A transparent photonic device or a sensor for chemical or biological sensing comprising the metamaterial is also provided.
