Several types of common polymers were deposited on glass slides sililated with organofunctional silanes. The extent of surface coverage, adsorbed layer thickness and topology were experimentally determined. The strength of polymer interaction with the silane treated glass was investigated using contact-mode AFM. The interaction strength to the surface was found to be dominated by hydrophobic/hy...

Bacteriorhodo sin is an integral membrane light-driven proton pump from ~aLbucter ium ~ o b i u m . It consists of seven transmembrane helices, surrounding a central proton translocation channel, in a 1:l complex with a retinal chromophore. The structure of the transmembrane helices has been resolved by high-resolution electron cryo-microscopy [ 11. We have investigated the amphipathic nature o...

Polymerizable ionic liquid monomer pairs were designed and copolymerized on silica as a new strategy to prepare multifunctional hybrid materials in hydrophobic and hydrophilic interaction chromatographies with enhancements of selectivity and stability.

We study by molecular dynamics simulations the wetting/dewetting transition and the dependence of the free energy on distance between plates that contain both hydrophobic and hydrophilic particles. We show that dewetting and strength of hydrophobic interaction is very sensitive to the distribution of hydrophobic and hydrophilic domains. In particular, we find that plates characterized by a larg...
