Mechanosensitive Fluorescent Probes to Image Membrane Tension in Mitochondria, Endoplasmic Reticulum, and Lysosomes

Suliana Manley, Stefan Matile, Dora Mahecic

Measuring forces inside cells is particularly challenging. With the development of quantitative microscopy, fluorophores which allow the measurement of forces became highly desirable. We have previously introduced a mechanosensitive flipper probe, which re ...

Molecular structure and function of myelin protein P0 in membrane stacking

Henning Paul-Julius Stahlberg

Compact myelin forms the basis of nerve insulation essential for higher vertebrates. Dozens of myelin membrane bilayers undergo tight stacking, and in the peripheral nervous system, this is partially enabled by myelin protein zero (P0). Consisting of an im ...

Microfluidic fabrication of vesicles with hybrid lipid/nanoparticle bilayer membranes

Esther Amstad

Hybrid lipid/nanoparticle membranes are suitable model systems both to study the complex interactions between nanoparticles and biological membranes, and to demonstrate technological concepts in cellular sensing and drug delivery. Unfortunately, embedding ...

Clustering on Membranes: Fluctuations and More

Julian Charles Shillcock

Clustering of extracellular ligands and proteins on the plasma membrane is required to perform specific cellular functions, such as signaling and endocy- tosis. Attractive forces that originate in perturbations of the membrane’s phys- ical properties contr ...

Fluorescence Imaging For Ultrafiltration Of Individual Nanoparticles From A Colloidal Solution In Track Membranes

We have used fluorescence nanoscopy for direct imaging of adsorption of individual colloidal quantum dots of diameter similar to 10 nm (spherical core/shell CdSeS/ZnS semiconductor nanocrystals, functionalized by organic oleic acid ligands) in nanopores of ...

Optical Antenna-Based Fluorescence Correlation Spectroscopy to Probe the Nanoscale Dynamics of Biological Membranes

Jürgen Brugger, Pamina Winkler, Valentin Flauraud, Raju Regmi

The plasma membrane of living cells is compartmentalized at multiple spatial scales ranging from the nano- to the mesoscale. This nonrandom organization is crucial for a large number of cellular functions. At the nanoscale, cell membranes organize into dyn ...

Improved Analytical Model of Hyperelastic Magnetic Membrane

Yves Perriard, Yoan René Cyrille Civet, Louis Antoine Masson, Guillaume Paul-André Burnand, Cécile Gisèle Aimée Jeannine Cuchet

This paper proposes an analysis of multi-factor fabrications of magnetic membranes. In order to acquire some knowledge about the influence of fabrication factors, an analysis is performed using a Design of Experiment (DoE) methodology. The latter is applie ...

Red blood cells ageing markers: a multi-parametric analysis

Gerardo Turcatti, Niels Erik Lion, Benjamin Rappaz, David Crettaz, Michel Prudent, Manon Sandra Bardyn

Background. Red blood cells collected in citrate-phosphate-dextrose can be stored for up to 42 days at 4 degrees C in saline-adenine-glucose-mannitol additive solution. During this controlled, but nevertheless artificial, ex vivo ageing, red blood cells ac ...

Transient Nanoscopic Phase Separation in Biological Lipid Membranes Resolved by Planar Plasmonic Antennas

Jürgen Brugger, Pamina Winkler, Valentin Flauraud, Raju Regmi

Nanoscale membrane assemblies of sphingolipids, cholesterol, and certain proteins, also known as lipid rafts, play a crucial role in facilitating a broad range of important cell functions. Whereas on living cell membranes lipid rafts have been postulated t ...

Mechanism of Shiga Toxin Clustering on Membranes

Julian Charles Shillcock

The bacterial Shiga toxin interacts with its cellular receptor, the glycosphingolipid globotriaosylceramide (Gb3 or CD77), as a first step to entering target cells. Previous studies have shown that toxin molecules cluster on the plasma membrane, despite th ...
