SERS platforms coated with aluminum are used in combination with silicone samplers and tunable solvents. The thesis is built upon three research lines with specific and progressive objectives. The first refers to the fabrication of the sampling devices. The second focuses on the detection of degradation markers from the surface of plastic-based contemporary artworks, aiming to develop minimally-invasive sampling tools for preventive conservation. The third expands the research towards a variety of small molecules and explores the limitations of the sampling method in applications in situengAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/SERS sensorssmall molecules detectioncultural heritageMaterias::Investigación::22 Física::2210 Química física::221090 Química-física de polímerosMaterias::Investigación::23 Química::2301 química analítica ::230117 Espectroscopia Ramndoctoral thesisopen access
