Abstract Text:
Life occurs in three dimensional turbid aqueous systems. A cell consists for ~60 % of water and contains many organelles and interfaces. The average distance between two molecules, or a molecule and a membrane interface is approximately 1 nm. The molecular, structural, dynamic, and biological properties of water, aqueous systems and aqueous interfaces are essential in understanding the complexity of life, and our ability to harness its features for novel (nano)technologies.

Nonlinear light scattering and microscopy methods can be used to gain label-free molecular level information about liquid aqueous systems and nanoscopic interfaces in turbid media and living cells. The usefulness of these methods will be illustrated around a few questions relating to the intriguing response of water to charge on various levels:

• Does water behave charge asymmetrically?
• Can we understand the role of water in interface stabilization / membrane formation?
• Can the response of water be used to probe membrane processes in living cells?

Is it possible to schedule my contribution on Monday or Tuesday (in the morning - with an eye on jetlag).
