Abstract:
Solvation is an omnipresent process both in our daily life and in the natural sciences. At the atomic level, the primary steps of solvation are the attraction and binding of ions or molecules of a solute to molecules or atoms of a solvent. Hitherto, these steps have not been observed in real time.

I will present recent experimental results that have enabled us to observe the solvation dynamics of a single alkali cation ion in liquid helium with atomic resolution and on the natural femtosecond time scale. A single Na+ is created instantly at the surface of a liquid He nanodroplet and we measured in real time the gradual attachment of individual He atoms to the ion.  In addition, we determined how fast the solvent-solute binding energy is dissipated from the local region around the alkali ion [1].

Abstract:
A large number of therapeutically attractive target proteins is shielded by cellular membranes. Many of these targets turned out to be undruggable with small molecules and due to membrane shielding they are not accessible with large biologics. This triggered the search for molecules which combine the enhanced surface recognition capabilities of biologics with the ability to penetrate cellular membranes. A promising strategy towards this goal involves the use of protein-inspired scaffolds that recapitulate small tertiary structures and facilitate miniaturization to support cellular uptake. Proteins are natural scaffolds defined by a hierarchy of structural complexity and have evolved to manifest unique functional characteristics e.g., molecular recognition properties that enable high binding affinity and selectivity.[1,2] Utilizing these features, proteins have been used as a starting point for the design of bioactive reagents in drug discovery. The lecture will describe design approaches towards bioactive proteomimetics using a human oncogene[3] and a bacterial target protein[4] as example. In both cases, the installation of cell permeability was essential for achieving bioactivity.
