Swelling Behavior and Nanomechanical Properties of (Peptide-Modified) Poly(2-hydroxyethyl methacrylate) and Poly(poly(ethylene glycol) methacrylate) Brushes
Harm-Anton Klok, Kislon Voitchovsky, Nicolas Bertrand Schüwer, Solenne Desseaux, Juan Pablo Hinestrosa Salazar
Poly(2-hydroxyethyl methacrylate) (PHEMA) and poly(poly(ethylene glycol) methacrylate) (PPEGMA) brushes represent a class of thin, surface-tethered polymer films that have been extensively used e.g. to generate non-biofouling surfaces or as model systems t ...
2016Thermally-nucleated self-assembly of water and alcohol into stable structures at hydrophobic interfaces
Francesco Stellacci, Michele Ceriotti, Kislon Voitchovsky, Daniele Giofré
At the interface with solids, the mobility of liquid molecules tends to be reduced compared with bulk, often resulting in increased local order due to interactions with the surface of the solid. At room temperature, liquids such as water and methanol can f ...
Nature Publishing Group2016In-situ mapping of the molecular arrangement of amphiphilic dye molecules at the TiO2 surface of dye sensitized solar cells
Ursula Röthlisberger, Francesco Stellacci, Ivano Tavernelli, Nicolas Tétreault, Kislon Voitchovsky, Negar Ashari Astani, Hauke Arne Harms
Amphiphilic sensitizers are central to the function of dye-sensitized solar cells. It is known that the cells performance depends on the molecular arrangement and the density of the dye on the semiconductor surface, but a molecular-level picture of the cel ...
2015Growth and dissolution of calcite in the presence of adsorbed stearic acid
Francesco Stellacci, Georg Fantner, Kislon Voitchovsky, Blake William Erickson, Maria Ricci, Juan José Segura Sugranes
The interaction of organic molecules with the surface of calcite plays a central role in many geochemical, petrochemical and industrial processes and in biomineralization. Adsorbed organics, typically fatty acids, can interfere with the evolution of calcit ...
American Chemical Society2015Trace concentration - Huge impact: Nitrate in the calcite/Eu(III) system
Kislon Voitchovsky, Moritz Schmidt
The interactions of trivalent lanthanides and actinides with secondary mineral phases such as calcite is of high importance for the safety assessment of deep geological repositories for high level nuclear waste (HLW). Due to similar ionic radii, calcium-be ...
Elsevier2014Water-induced correlation between single ions imaged at the solid-liquid interface
Kislon Voitchovsky, Peter Spijker, Maria Ricci
When immersed into water, most solids develop a surface charge, which is neutralized by an accumulation of dissolved counterions at the interface. Although the density distribution of counterions perpendicular to the interface obeys well-established theori ...
Nature Publishing Group2014Lipid tail protrusions mediate the insertion of nanoparticles into model cell membranes
Francesco Stellacci, Paulo Henrique Jacob Silva, Kislon Voitchovsky, Javier Reguera Gomez, Maria Ricci
Recent work has demonstrated that charged gold nanoparticles (AuNPs) protected by an amphiphilic organic monolayer can spontaneously insert into the core of lipid bilayers to minimize the exposure of hydrophobic surface area to water. However, the kinetic ...
Nature Publishing Group2014Adsorbed and near surface structure of ionic liquids at a solid interface
Kislon Voitchovsky, Juan José Segura Sugranes
The structure of solid-ionic liquid (IL) interfaces has been characterised with unprecedented clarity by employing a range of atomic force microscopy (AFM) imaging techniques and tip pressures appropriate for the system under study. Soft contact and amplit ...
Royal Society of Chemistry2013Electrical Method to Quantify Nanoparticle Interaction with Lipid Bilayers
Francesco Stellacci, Paulo Henrique Jacob Silva, Randy Patrick Carney, Kislon Voitchovsky, Tamara Michael Carney
Understanding as well as rapidly screening the interaction of nanoparticles with cell membranes is of central importance for biological applications such as drug and gene delivery. Recently, we have shown that "striped" mixed-monolayer-coated gold nanopart ...
American Chemical Society2013Anharmonicity, solvation forces, and resolution in atomic force microscopy at the solid-liquid interface
Solid-liquid interfaces are central to nanoscale science and technology and control processes as diverse as self-assembly, heterogeneous catalysis, wetting, electrochemistry, or protein function. Experimentally, measuring the structure and dynamics of soli ...
