A mobile set-up for simultaneous and in situ neutron reflectivity, infrared spectroscopy, and ellipsometry studies
Neutron reflectivity (NR) is a non-destructive technique for detailed analysis of layered structures on molecular length scales providing thickness, density, roughness and composition of individual layers or components of adsorbed films. However, information on specific molecular groups or their conformation is not accessible. Moreover, NR cannot determine large layer thicknesses, and its time resolution is limited, making it challenging to resolve the kinetics of fast surface processes. The goal of this proposal is to implement an integrated portable sample environment for simultaneous in situ characterization including (i) NR for structural analysis, (ii) infrared spectroscopy in total reflection geometry (ATR-IR) for the determination of molecular entities and their conformation, and (iii) spectroscopic ellipsometry (SE) for rapid and independent measurement of layer thicknesses. The high potential of this approach will be shown by studying (i) the impact of metal and metal oxide nanoparticles on lipid membranes and membrane proteins, to identify potential mechanisms of nanotoxicity, and (ii) the pH-dependent swelling and tunable protein resistance of polyelectrolyte layers.
