Glassy dynamics of water at interface with biomolecules: A Mode Coupling Theory test

Abstract [en]

We study the slow dynamics of hydration water upon cooling in two di ff erent biological aqueous solutions, one containing a molecule of lysozyme and another with trehalose molecules. In particular we test if the glassy behaviour of these solutions ful fi ls the predictions of the popular Mode Coupling Theory of glassy dynamics. In particular we test the Time Temperature Superposition Principle and the matching of the exponents of the theory. Our results con fi rm that this theory is able to describe the dynamical behaviour of supercooled water also in non ideal cases as the ones under investigation in the region of mild supercooling.
