6. Electronic Energy Migration/Transfer as a Tool to Explore Biomacromolecular Structures
Sammanfattning : Fluorescence-based techniques are widely used in bioscience, offering a high sensitivity and versatility. In this work, fluorescence electronic energy migration/ transfer is applied to measure intramolecular distances in two types of systems and under various conditions. LÄS MER
7. Nonlinear optical techniques for ultrafast laser diagnostics : Development of femtosecond LIF, LIGS, CARS and backward lasing
Sammanfattning : The thesis work concerns development and application of four versatile nonlinear optical techniques, based on exploiting ultrashort laser pulses, for diagnostic purposes in gases and flames. The four techniques, all laser-based, are two-photon laser-induced fluorescence (TPLIF), hybrid femtosecond/nanosecond (fs/ns) rotational coherent anti-Stokes Raman scattering (fs/ns RCARS), fs-laser-induced grating spectroscopy (fs-LIGS), and backward lasing.

8. New insights in contact allergy and drug delivery. A study of formulation effects and hapten targets in skin using two-photon fluorescence microscopy
Sammanfattning : The skin is a remarkable barrier, protecting us from invasion of e.g. harmful microorganisms and UV-radiation. However, the skin is not adopted to resist repeated exposure to the multitude of xenobiotics introduced into modern society. LÄS MER
9. Non-linear Optical Microscopy and Spectroscopy for Biomedical Studies
Sammanfattning : This thesis is based on the application of non-linear optical microscopy and spectroscopy techniques within biomedical research. Non-linear optical microscopy gives the possibility of exciting fluorophores using near infrared light. LÄS MER
10. Unconventional Modulation of Diarylethene Photoswitches
Sammanfattning : Light can be manipulated and modulated to fit a particular need or application, such as overcoming a spectral mismatch when facilitating a high energy photochemical reaction. This can be of use in various applications, including solar energy conversion and biological contexts. LÄS MER
