Suitability of Ag‐agar gel for the micro‐extraction of organic dyes on different substrates: the case study of wool, silk, printed cotton and a panel painting mock‐up

A surface‐enhanced Raman spectroscopy (SERS) substrate made of agar gel coupled with silver nanoparticles has been applied to the micro‐extraction and the ultra‐sensitive detection of dyes on pieces of textile of different nature (silk, wool, and printed cotton) and on a mock‐up panel painting.
