Langmuir, 2008
The interaction between a colloidal polystyrene particle mounted on an AFM cantilever and a hydrophilic and a hydrophobic surface in aqueous solution is investigated. Despite the apparent simplicity of these two types of systems a variety of different types of interactions are observed.

Quantum Mechanics Study on Hydrophilic and Hydrophobic Interactions in the Trivaline–Water System
The Journal of Physical Chemistry B, 2018With the aim to elucidate hydrophobic effects in the unfolded state of peptides, DFT-M062X computations on the Val3H+· nH2O ( n up to 22) clusters have been accomplished. As far as the main chain is concerned, four conformers with β-strand and/or polyproline type II conformations, PPII (indicated as β-β, β-PPII, PPII-β, and PPII-PPII), have been found ...

Solvation free energy is a driving force that plays an important role in the stability of biomolecular conformations. Currently, the implicit solvent model is widely used to calculate solvation energies of biomolecules such as proteins. However, for proteins, the implicit solvent calculation does not provide much detailed information since a protein is

Specific Ion Effects on the Interaction of Hydrophobic and Hydrophilic Self-Assembled Monolayers
Langmuir, 2018Interactions between mineral surfaces and organic molecules are fundamental to life processes. The presence of cations in natural environments can change the behavior of organic compounds and thus alter the mineral-organic interfaces. We investigated the influence of Na+, Mg2+, Ca2+, Sr2+, and Ba2+ on the interaction between two models, self-assembled ...

In nature, selective interactions between chiral amino acids and crystals are important for the formation of chiral biominerals and provide insight into the mysterious origin of homochirality. Here, we show that chiral amino acids with different hydrophilicities/hydrophobicities exhibit different chiral selectivity preferences in the dynamically ...

Study of peptides adsorption on surfaces remains a current challenge in literature. A complementary approach, combining X‐ray photoelectron spectroscopy (XPS) and time‐of‐flight secondary ion mass spectrometry (ToF‐SIMS) was used to investigate the antimicrobial peptide nisin adsorption on hydrophilic and hydrophobic surfaces.

The importance of water interactions with proteins in food systems is well documented. A controversy exists, however, as to the nature of these interactions and the effect of protein structural changes on them. To clarify these questions, a method has been developed for determining hydration from the protein concentration-dependence of deuteron ...

Macromolecules, 2009
The performance of biomaterials in contact with biological systems can be greatly affected by hydrophobic interactions at the interface between the biomaterial surface and surrounding biomolecules. Polymer brushes can function as a protective layer, preventing such interfacial hydrophobic interactions.

Here we study experimentally and by simulations the interaction of monovalent organic and inorganic anions with hydrophobic and hydrophilic colloids. In the case of hydrophobic colloids, our experiments show that charge inversion is induced by chaotropic inorganic monovalent ions but it is not induced by kosmotropic inorganic anions. For organic anions,
