The two first chapters have been devoted to the optimization of methods for the determination of several elements by ICP-MS (use of dried blood spot, DBS; and discrete sampling followed to introduction in ICP-MS). In the second part of this thesis regarding proteomics, several proteins for differentiating three groups of population (healthy people, AD patients, and MCI patients) have been found. In a final chapter, LA conditions have been optimized for the determination of metals in the isoforms of two proteins [Serotransferrin (TRFE) and Keratin type II cytoskeletal 1 (K2C1)] after 2D electrophoresis.engAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/Alzheimer´s diseaseProteomicMulti-element determinationSerumMaterias::Investigación::23 Química::2301 química analítica ::230110 Espectroscopia de masasMaterias::Investigación::23 Química::2301 química analítica ::230199 Proteómicadoctoral thesisopen access
