  1. 1. Miniaturized localized surface plasmon resonance biosensors

    Författare :Si Chen; Chalmers University of Technology; []
    Nyckelord :colloidal lithography; Surface plasmon resonance; biosensing; electron beam lithography; single molecule; hyperspectral imaging; photo functionalization;

    Sammanfattning : Abstract Reliable and sensitive biosensors are required for fast and accurate diagnostics. Localized surface plasmon resonances (LSPRs) in noble-metal nanoparticles possess very high refractive index sensitivity close to the metal surface and therefore constitute an attractive biosensing platform.

  3. 3. Molecular Alligator Clips: A Study of Metal-Molecule Contacts for Molecular Electronics

    Författare :Anton Grigoriev; Chalmers University of Technology; []
    Nyckelord :nonequilibrium Green s functions; single crystal surfaces; nanostructures; chemisorption; selenium; low index single crystal surface; density functional calculations; organic molecules; sulphur; nonequilibrium electron transport; gold;

    Sammanfattning : In this thesis we present a computational study of the elementary building blocks for molecular electronics, interconnected electronic devices with critical dimensions below 5 nm. Building electronic circuits on that scale requires stable connection between the various parts of the device and to the macroscopic metal electrodes, needed for power supply, support and integration with conventional electronics.
