IDENTIFICATION OF COEXISTING INDIGO SPECIES IN AN ANCIENT GREEN THREAD USING DIRECT PLASMON-ENHANCED RAMAN SPECTROSCOPY
ABSTRACT A green ancient thread sample from a Chilean mummy turban was analyzed by plasmon-enhanced Raman scattering spectroscopy using a direct drop-colloidal method. The enhanced-Raman signals in the sample are associated with biomolecules from the thread and two coexisting dyes, indigo and leuco-...
