1. 1. Contact Allergy to Textile Dyes - Clinical and Chemical Studies on Disperse Dyes

   Författare :Kristina Morgardt-Ryberg; Yrkes- och miljödermatologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Disperse Blue 106; contact allergy; Disperse Orange 3; disperse dyes; Disperse Blue 124; TLC; textile-related skin problems; textile dye mix; PPD; HPLC; impurities;

   Sammanfattning : Disperse dyes are common sensitizers among textile dyes. Contact allergy to disperse dyes has been documented in studies carried out in southern Europe, however, corresponding studies have not been performed in the Scandinavian countries. LÄS MER

3. 2. Cellular Dyes and Bioactive Peptides - Cell Membrane Interactions and Cellular Uptake

   Författare :Maria Matson Dzebo; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Membrane Interactions; Spectroscopy; Cell-Penetrating Peptides; Bioactive Peptides; Cell Membrane; Confocal Laser Scanning Microscopy; Cellular Uptake; AF-16; Voltage-Sensitive Dyes; Cell Dyes; Antisecretory Factor; Ruthenium Complexes; Isothermal Titration Calorimetry; Flow-Cytometry;

   Sammanfattning : Knowledge about mechanisms behind interactions of molecules with biomembranes and cellular uptake is very important for understanding biological processes and for drug design. The work described in this thesis has focused on interactions of cellular dyes and bioactive peptides with cells and the cell membrane. LÄS MER

4. 3. Determination of Banned Azo Dyes in Leather

   Författare :Lars-Henric Ahlström; Centrum för analys och syntes; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Analytisk kemi; Analytical chemistry; extraction; azo dyes; aromatic amines;

   Sammanfattning : Dyes are commercially indispensable and the expanding industry offers a complete palette of colors. Azo dyes constitute the largest chemical class of synthetic dyes because of their versatility, low price, and ease of production. LÄS MER

5. 4. Groove-binding Unsymmetrical Cyanine Dyes for DNA Applications

   Författare :Maja Eriksson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; polarized spectroscopy; bacteriophage T5; cryo-transmission electron microscopy; dynamic light scattering; DNA; intercalation; cyanine dyes; groove-binding; fluorescence spectroscopy; gel electrophoresis;

   Sammanfattning : This work focuses on interactions between DNA and a group of newly developed unsymmetrical cyanine dyes. The aim of the work was to discover fluorescent dyes that can be used in biophysical studies of natural DNA where minimum perturbation of the DNA-helix is essential, where a slow dissociation rate of the dyes is needed and where the ionic strength is an important parameter.

7. 5. Luminescence properties of flexible conjugated dyes

   Författare :Jonas Sjöqvist; Patrick Norman; Mikael Lindgren; Jacob Kongsted; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; force field; molecular dynamics; linear absorption; QM MM; absorption spectrum; emission spectrum; water solvation; stokes shift;

   Sammanfattning : In this licentiate thesis the luminescence properties of two flexible conjugated dyes have been studied. The first, Pt1, is a platinum(II) acetylide chromophore used in optical power limiting materials. LÄS MER
