Laser desorption/ionization (LDI) mass spectrometry on porous silicon (MS) is a promising alternative to matrix-assisted laser desorption/ionization (MALDI) MS for the study of small molecules. Indeed, LDI-MS employs nanostructured porous silicon surfaces instead of organic matrices to assist the analyte desorption/ionization, which greatly limits the interference generated in the low m/z range, and thus allows the analysis of low molecular weight compounds. In addition, the use of porous silicon surface has the potential to provide other valuable advantages, such as the dual-polarity capabilities of the substrate, the compatibility with multimodal experiments and the possibility to functionalize the surface to improve the selectivity or the limit of detection of the technique. However, the use of porous silicon surfaces in real applications first requires a good understanding of the different aspects of the LDI-MS technique, including for example the impact of the nanosubstrate morphology on the desorption/ionization process harshness (analytes fragmentation). The objective of this Master’s thesis is to gain a better understanding of the desorption/ionization process occurring on porous silicon surfaces to ultimately optimize them for the LDI-MS analysis of small molecules such as metabolites or organic pollutants.

2D nanomaterials are a relatively populous and ever-expanding class of innovative materials with disruptive potential for different application contexts. Although for some of them, such as graphene, various possible implementations have already been explored in different application fields, others, (e.g., Mxenes), are still relatively at an infantile stage with regard to handling, stability, exploitation, processing and practical use in devices and structures with higher dimensionality.In any case, regardless of the specific nature of each of these materials, their degree of purity and structure (mono-layers/few-layers/multi-layers) and their level of maturity, they all share the same challenges since their onset, such as processing, patterning, transfer and integration in devices, allowing smart exploitation of their unique properties, incorporation in matrices of different nature for the synthesis of nano-composites, and so on.Accordingly, this book aims to showcase research papers and review articles outlining recent progress and innovative approaches for 2D nanomaterials synthesis and/or processing, preparatory to their assembly or integration into devices, microstructures, microsensors and composites for different application fields.
