Effects of thermal, mechanical, and electrostatic perturbations on lipid membrane hydration investigated by second harmonic imaging

Seonwoo Lee

Hydrated lipid bilayer membranes are crucial components of cells and organelles, serving as the outer boundary that separates the cellular components from the extracellular environment. Lipid membranes regulate their structures and functions by dynamically ...

High throughput wide field second harmonic imaging of giant unilamellar vesicles

Sylvie Roke, Maksim Eremchev, David Roesel, Pierre-Marc Jean Marie Dansette

Cell-sized giant unilamellar vesicles (GUVs) are an ideal tool for understanding lipid membrane structure and properties. Label-free spatiotemporal images of their membrane potential and structure would greatly aid the quantitative understanding of membran ...

Homogenization theory captures macroscopic flow discontinuities across Janus membranes

François Gallaire, Pier Giuseppe Ledda, Giuseppe Antonio Zampogna, Kevin Wittkowski

Janus membranes, thin permeable structures with chemical and geometrical asymmetric properties, show great potential in industrial separation processes. Yet the link between the micro- and macro-scale behaviours of these membranes needs to be established r ...

Micro- or nanostructured optical element

Niels Quack, Dorian Giraud Herle

A micro- or nanostructured optical element (1) is proposed comprising: a membrane (3) with an array of holes (5), the membrane (3) comprising a membrane light wave facing surface; an array of pillars (7) sized and shaped such that a respective pillar (7) i ...

Structure of a membrane-bound menaquinol:organohalide oxidoreductase

Christof Holliger, Henning Paul-Julius Stahlberg, Julien Maillard, Dongchun Ni, Babatunde Edukpe Ekundayo, Lorenzo Cimmino

Organohalide-respiring bacteria are key organisms for the bioremediation of soils and aquifers contaminated with halogenated organic compounds. The major players in this process are respiratory reductive dehalogenases, corrinoid enzymes that use organohali ...

Evolution of the electrical double layer with electrolyte concentration probed by second harmonic scattering

Sylvie Roke, Arianna Marchioro, Bingxin Chu, Marie Bischoff

Investigating the electrical double layer (EDL) structure has been a long-standing challenge and has seen the emergence of several sophisticated techniques able to probe selectively the few molecular layers of a solid/water interface. While a qualitative e ...

Structural diversity of photoswitchable sphingolipids for optodynamic control of lipid microdomains

Samuel Mendes Leitão

Sphingolipids are a structurally diverse class of lipids predominantly found in the plasma membrane of eukaryotic cells. These lipids can laterally segregate with other rigid lipids and cholesterol into liquid-ordered domains that act as organizing centers ...

Simultaneous membrane and RNA binding by Tick-Borne Encephalitis Virus capsid protein

Sarah Victoria Barrass

Tick-borne encephalitis virus is an enveloped, pathogenic, RNA virus in the family Flaviviridae, genus Flavivirus. Viral particles are formed when the nucleocapsid, consisting of an RNA genome and multiple copies of the capsid protein, buds through the end ...

Simultaneous Electrophysiology and Imaging Reveal Changes in Lipid Membrane Thickness and Tension upon Uptake of Amphiphilic Gold Nanoparticles

Francesco Stellacci, Xufeng Xu, Paulo Henrique Jacob Silva, Camilla Servidio

Amphiphilic gold core nanoparticles (AmNPs) striped with hydrophilic 11-mercapto-1-undecanesulfonate (MUS) and hydrophobic 1-octanethiol (OT) ligands are promising candidates for drug carriers that passively and nondisruptively enter cells. Yet, how they i ...
