Everyone has seen a fluorescent painting, but did you know fluorescence (or more-generally photoluminescence) is an effect that may be used to study cultural heritage? Fluorescence phenomena give information about a broad spectrum of materials in a non-invasive manner. Continue reading A fluorescent party: Fluorescence spectroscopy for non-invasive characterization of artwork
Analysis of dyes in textiles is particularly challenging given the complex nature of the mixtures used in their weaving. A novel separation method based on 2-Dimensional Liquid Chromatography shows promise for unraveling what illusive colorants lie within the weave.

The analysis of dyes and lakes is a challenging task for conservation scientists. Nanoparticles and nanocomposites have become a powerful tool to increase the power of spectroscopic techniques, exemplified with SERS. This method not only improves the detection limit but also allows non-invasive analyses. Continue reading Nano-what? Silver nanoparticle gel for identifying pigments
