Research group Ulrika Nilsson group
Our research is focused on the development of analytical methods and techniques enabling studies and measurements of compounds involved in skin sensitization (contact allergy).
We are especially interested in analyzing complex dye mixes in textiles. Some pigments and also substances used when applying dye to textiles are known to cause allergies. We are developing methods to better understand the levels of chemicals and indentifying allergens.
Examples of skin-sensitizers of special interest are fragrance hydroperoxides, isothiocyanates, resin acids from colophonium, and textile pollutants. High-sensitivity/high-selectivity methods, for example 2D-reversed phase/normal phase HPLC/MS and SPME/GC/MS, are developed to measure trace amounts of skin sensitizers in highly complex commercial products and materials.
