Interface-assisted laser desorption and ionization of molecules on nanoparticles (S06)

• Subject Area: Optics, Quantum Optics and Physics of Atoms, Molecules and Plasmas ; Analytical Chemistry
• Term: since 2022
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 441234705

In project S06, we will explore novel routes for the efficient and non-destructive laser desorption of health- and climate relevant molecules from the surface of aerosol samples and from individual (nano-)particles for their detection using mass spectrometry. The program follows a systematic approach, starting with simple nanostructures and deposited spheres, stepwise increasing the target's complexity towards real-world aerosols in a particle beam. For each step, experiments and theoretical activities are complementarily designed to provide a detailed physical picture and maximum control of the underlying processes with the aim of non-destructive and efficient desorption and ionization in aerosol mass spectrometry.
