Identification of coexisting indigo species in an ancient green thread using direct plasmon-enhanced Raman spectroscopy (2020)
Celis, Freddy; Tirapegui, Cristian; García, Macarena; Aracena, Andrés; Aliaga, Álvaro. E.; Campos-Vallette, Marcelo (Sociedad Chilena de Quimica, 2020-06-30)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 ... -
