Nano-what? Silver nanoparticle gel for identifying pigments

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

Green slime invasion deterred by laser guns! How finely-tuned light can be used to clean marble

Laser light can be used to blast grime off stone surfaces without affecting the stone substrate underneath. Although laser cleaning can be used in conjunction with other methods to remove different types of contaminants, here we highlight an article that uses only laser cleaning to remove biofilm from a marble statue. Continue reading Green slime invasion deterred by laser guns! How finely-tuned light can be used to clean marble
