Surface topography dependence of biomolecular hydrophobic hydration

Article Abstract:

It has been possible to show a topography dependence for hydrophobic hydration of a molecular surface. This research involved making computer simulations of the interaction between the polypeptide melittin and water. These simulations show that the two different hydration structures also exist near a biomolecular surface. It is suggested that the temperature dependence of hydrophobic interaction connected with melittin hydration should be clearly different from that connected with small-molecule hydration even in the case of essentially complete enthalpy-entropy compensation at a specific temperature.

Selection of peptides with semiconductor binding specificity for directed nanocrystal assembly

Article Abstract:

It has been been possible to demonstrate the power of using phage-display libraries to identify, develop and amplify binding between organic peptide sequences and inorganic semiconductor substrates. Combinatorial phage-display libraries are effective in evolving peptides that bind to a range of semiconductor surfaces with high specificity.
