  1. 6. Diffractive Optical Elements: Fabrication, Replication, and Applications and Optical Properties of a Visual Field Test

    Författare :Fredrik Nikolajeff; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; perimetry; beam homogenizing; antireflection; high-pass spatial frequency target; proximity effect; electron beam lithography; replication; successive development; diffractive optical element; axicon;

    Sammanfattning : This thesis mainly treats the fabrication, replication and applications of diffractive optical elements. A smaller part deals with optical properties of a visual field test. Diffractive optical elements are computer-generated micro-optic components that use diffraction to manipulate light. LÄS MER

  3. 7. Miniaturized localized surface plasmon resonance biosensors

    Författare :Si Chen; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; 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.

  4. 8. Novel Functionalized Nanopores for Plasmonic Sensing

    Författare :Bita Malekian; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; extinction spectra; nanopores; proteins; nanocaves; nanowells; surface plasmon resonance; nuclear pore complex; colloidal lithography; nanoplasmonic sensor; label-free sensing; electron beam lithography; plasmonic nanostructures;

    Sammanfattning : Nanoplasmonic sensors offer a label-free platform for real-time monitoring of biomolecular interactions by tracking changes in refractive index through optical spectroscopy. However, other surface sensitive techniques such as conventional surface plasmon resonance offer similar capabilities with equal or even better resolution in terms of surface coverage. LÄS MER
