Cutting-Edge Molecular Approaches for Cultural Heritage - From Paleoproteomics to Advanced SERS Sensors, the Next-Gen Analytical Technologies

Professor Favero’s group is dedicated to pioneering advanced technologies at the intersection of science and cultural heritage. Their research spans the creation of cutting-edge active SERS substrates for ultra-sensitive detection and identification of pollutants in museum environments, development of innovative nanomaterials up to new advanced methodology in paleoproteomics and study of ancient organic residues using integrated omics approaches.

Comparison between silver and gold nanoparticles stabilized with negatively charged hydrophilic thiols: SR-XPS and SERS as probes for structural differences and similarities

The electronic and molecular structure, as well as the chemical nature of noble metal (silver, gold) nanoparticles (AgNPs, AuNPs) stabilized by the negatively charged hydrophilic organic thiol Sodium 3-mercapto-1-propanesulfonate (3-MPS) has been probed combining Synchrotron Radiation-induced X-ray Photoelectron Spectroscopy (SR-XPS) and Surface Enhanced Raman Spectroscopy (SERS).

Dyes from the ashes. Discovering and characterizing natural dyes from mineralized textiles

Vesuvius eruption that destroyed Pompeii in AD 79 represents one of the most important events in history. The cataclysm left behind an abundance of archeological evidence representing a fundamental source of the knowledge we have about ancient Roman material culture and technology.
A great number of textiles have been preserved, rarely maintaining traces of their original color, since they are mainly in the mineralized and carbonized state. However, one outstanding textile sample displays a brilliant purple color and traces of gold strips. Since the purple was one of the
