A KcsA/MloK1 Chimeric Ion Channel Has Lipid-dependent Ligand-binding Energetics

Background: The mechanism of ligand gating in physiologically important cyclic nucleotide-modulated channels is unknown. Results: We constructed and purified a chimeric ion channel with activity modulated by cAMP and used it to measure ligand-binding energ ...

Adding diversity to ruthenium(II)-arene anticancer (RAPTA) compounds via click chemistry: the influence of hydrophobic chains

Paul Joseph Dyson, Anna Katherine Renfrew

The application of click chemistry to develop libraries of organometallic ruthenium-arene complexes with potential anticancer properties has been investigated. A series of ruthenium-imidazole-triazole complexes, with hydrophobic tails, were prepared from a ...

The Orientation and Charge of Water at the Hydrophobic Oil Droplet-Water Interface

Sylvie Roke, Hilton Barbosa De Aguiar

We established the charge and structure of the oil/water interface by combining zeta-potential measurements, sum frequency scattering (SFS) and molecular dynamics simulations. The SFS experiments show that the orientation of water molecules can be followed ...

The orientation and charge of water at the hydrophobic oil droplet - Water interface

Sylvie Roke, Hilton Barbosa De Aguiar

We established the charge and structure of the oil/water interface by combining ?-potential measurements, sum frequency scattering (SFS) and molecular dynamics simulations. The SFS experiments show that the orientation of water molecules can be followed on ...

Investigation of molar volume and surfactant characteristics of water-soluble organic compounds in biomass burning aerosol

Athanasios Nenes

In this study, we characterize the CCN activity of the water-soluble organics in biomass burning aerosol. The aerosol after collection upon filters is dissolved in water using sonication. Hydrophobic and hydrophilic components are fractionated from a porti ...

Determination of surface properties of various substrates using TiO2 nanorod coatings with tunable characteristics

Raffaella Buonsanti

We present a novel approach to cover different substrates with thin light-sensitive layers that consist of org.-capped TiO2 nanorods (NRs). Such NR-based coatings exhibit an increasing initial hydrophobicity with increasing NR length, and they demonstrate ...

Sorption of hydrophobic organic compounds (HOC) in rapeseed oil bodies

Ian William Marison, Julien Boucher

Oil-bodies are minute plant organelles (0.5-2.0 mu m diameter) consisting of an oil core surrounded by a phospholipid monolayer/proteinaceous membrane. Oil-bodies have been isolated from rapeseed seeds and demonstrated to constitute a novel type of micro-c ...

Novel applications of poly(ethylene glycol)-bl-poly(propylene sulfide) block copolymers

Conlin O'Neil

Block copolymers are comprised of repeating chemical groups (blocks) which commonly contain at least one hydrophilic block coupled to at least one hydrophobic block, forming an amphipathic macromolecule. This molecular arrangement drives the self assembly ...

Size Limitations for the Formation of Ordered Striped Nanoparticles

Francesco Stellacci, Randy Patrick Carney, Jiwon Kim

A combination of immiscible molecules in the ligand shell of a gold nanoparticle (NP) has been shown to phase separate into a rippled structure; this phase separation can be used to direct the assembly of the NPs into chains. Here we demonstrate that only ...
