  1. 1. Total internal reflection ellipsometry : principles and applications

    Författare :Michal Poksinski; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Spectroscopic ellipsometry has been used under conditions of total internal reflection to form a new measurement technique called Total Internal Reflection Ellipsometry. When measurement settings are appropriate for surface plasmon resonance to occur it is possible to combine the advantages of both ellipsometry and surface plasmon resonance and obtain very high sensitivity and precision.

  3. 2. Total internal reflection ellipsometry

    Författare :Michal Poksinski; Uwe´ Beck; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : This thesis summarizes the work performed on the development and implementation of the optical measurement technique called total internal reflection ellipsometry (TIRE).The TIRE principle is based on spectroscopic ellipsometry performed under conditions of total internal reflection.

  4. 3. Colloidal interactions obtained from total internal reflection microscopy measurements and scattering data

    Författare :Moheb Nayeri; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; total internal reflection microscopy; colloidal stability; van der Waals interaction; Debye length; surfactants; depletion; scattering; colloidal stability;

    Sammanfattning : The scattering of radiation can be used to extract information about the interactions between colloidal (10^{-7}-10^{-3} cm radius) particles suspended in liquids. As colloidal interactions incorporate entropic effects they are weak and while system specific they are governed by a number of general mechanisms. LÄS MER

  5. 4. Photo-induced dark states influorescence spectroscopy – investigations & applications

    Författare :Andriy Chmyrov; Jerker Widengren; Johan Hofkens; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fluorescence correlation spectroscopy; triplet state; isomerisation; photobleaching; quenching; diffusion; total internal reflection; interface; Spectroscopy; Spektroskopi;

    Sammanfattning : This thesis focuses on investigations of transient dark states of fluorescentmolecules using spectroscopic techniques. The main purpose is to show andconvince the reader that transient dark states are not always a nuisance, butalso represent an additional source of information. LÄS MER

  7. 5. Probing Biomolecular Recognition at the Single Molecule Level

    Författare :Anders Gunnarsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; cell membrane; TIRFM; liposome; time-of-flight secondary ion mass spectrometry; membrane receptor; single molecule; TOF-SIMS; molecular recognition; DNA; barcode; total internal reflection; multiplexing;

    Sammanfattning : Specific recognition between biomolecular partners contributes to a multitude of biochemical signaling within and between cells. The aim of this work has been to investigate the possibility to probe biomolecular recognition reactions at the smallest possible scale, the single molecule level. LÄS MER
