Detection of degradation markers from polymer surfaces by a novel SERS-based strategy. Talanta, 191, 156-161. doi: 10.1016/j.talanta.2018.08.0460039-9140http://hdl.handle.net/10347/17653This paper provides new insights for the study of polymer degradation through the detection of markers released at the polymer surface using Al-coated SERS active substrates. Combining a nanodestructive sampling procedure with the SERS sensitivity allows achieving detection limits much lower than traditional polymer characterization techniques, opening the way to the use of SERS as part of an innovative strategy to diagnose surface degradation in polymeric museum artefacts. The method was applied to artificially photo-aged model polymers and to museum artworkseng© 2018 The Authors. Published by Elsevier B.V.
