pH drives electron density fluctuations that enhance electric field-induced liquid flow

Sylvie Roke, Saranya Pullanchery Sankara Narayanan, Sergey Kulik, Tereza Schönfeldová

Liquid flow along a charged interface is commonly described by classical continuum theory, which represents the electric double layer by uniformly distributed point charges. The electrophoretic mobility of hydrophobic nanodroplets in water doubles in magni ...

Second harmonic scattering of water in a biological context

Tereza Schönfeldová

Water is one of the most abundant molecules in the universe. It forms a hydrogen bond network with unique structure and dynamics. Hydrogen bonding is highly relevant to many biological processes including membrane formation, protein folding, adsorption, an ...

Charge Gradients around Dendritic Voids Cause Nanoscale Inhomogeneities in Liquid Water

Yixing Chen, Sylvie Roke, Nathan Dupertuis, Tereza Schönfeldová

Water is the matrix of life and serves as a solvent for numerous physical and chemical processes. The origins of the nature of inhomogeneities that exist in liquid water and the time scales over which they occur remains an open question. Here, we report fe ...

Ultrasensitive Label-Free Detection of Protein–Membrane Interaction Exemplified by Toxin-Liposome Insertion

Mircea Ioan Iacovache, Matteo Dal Peraro, Sylvie Roke, Halil Ibrahim Okur, Chan Cao, Tereza Schönfeldová

Measuring the high-affinity binding of proteins to liposome membranes remains a challenge. Here, we show an ultrasensitive and direct detection of protein binding to liposome membranes using high throughput second harmonic scattering (SHS). Perfringolysin ...

Lipid Melting Transitions Involve Structural Redistribution of Interfacial Water

Sylvie Roke, Filip Kovacik, Halil Ibrahim Okur, Tereza Schönfeldová

Morphological and gel-to-liquid phase transitions of lipid membranes are generally considered to primarily depend on the structural motifs in the hydrophobic core of the bilayer. Structural changes in the aqueous headgroup phase are typically not considere ...
