Molecular dynamics of a bioprotective fluid confined to nanopores — •Nicolas Ubrig¹, Rémi Busselez², René Berwanger¹, Denis Morineau², and Rolf Pelster¹ — ¹Fachrichtung 7.2, Experimentalphysik, Universität des Saarlandes, Postfach 151150, 66 041 Saarbrücken, Germany — ²GMCM, campus de Beaulieu, 35042 Rennes Cedex, France

We study structure and molecular dynamics of a bioprotective fluid. This is a solution of glycerol and trehalose , the glass transition of which depends on the mixing ratio. The fluid is confined in parallel rodlike nanopores of a silicon matrix. Different techniques such as temperature dependent NMR, Raman-, infrared- and dielectric spectroscopy are applied in order to detect confinement-induced deviations from the bulk behavior.
