Fluorogenic polymethine dyes by intramolecular cyclization
Pablo Rivera Fuentes, Annabell Martin
Fluorescence imaging plays a pivotal role in the study of biological processes, and cell -permeable fluorogenic dyes are crucial to visualize intracellular structures with high specificity. Polymethine dyes are vitally important fluorophores in singlemolec ...
Elsevier Sci Ltd2024Membrane specificity of the human cholesterol transfer protein STARD4
Charlotte Julie Caroline Gehin
STARD4 regulates cholesterol homeostasis by transferring cholesterol between the plasma membrane and endoplasmic reticulum. The STARD4 structure features a helix-grip fold surrounding a large hydrophobic cavity holding the sterol. Its access is controlled ...
Academic Press Ltd- Elsevier Science Ltd2024Osmosis-driven stiffening of structured hydrogels
Esther Amstad, Ran Zhao, Alexandra Thoma
Plant cells harness osmotic pressures to stiffen their leaves through strong turgor pressures. Key to this osmosisdriven stiffening is the confinement of liquids within semipermeable membranes that can regulate the transport of water molecules and ions. In ...
Elsevier2024A new self-adjustable glaucoma valve
Nikolaos Stergiopoulos, Stéphane Bigler, Julien Maxime Gerber, Soroush Rafiei
Introduction: Glaucoma, the leading cause of irreversible blindness globally, affects more than 70 million people across the world. When initial treatments prove ineffective, especially for cases with high intraocular pressure (IOP), the preferred approach ...
Frontiers Media Sa2024Charge-Selectively Permeable Self-Healing Microcapsules
Microcapsules possessing a selective permeability are well-suited vessels for conducting cell studies or chemical reactions that require selective exchanges of reagents over a prolonged time. Most currently reported microcapsules are single-use delivery ca ...
WILEY2023Selectively permeable microcapsules
Microcapsules are appealing containers for delivering active ingredients, such as drugs and cosmetics, or conducting chemical and biological reactions on a small scale. To control the timing and location of release of these encapsulants, the shells of micr ...
EPFL2023Time-Resolved Scanning Ion Conductance Microscopy and Single-Molecule Spectroscopy
The evolution of the 3D morphology is at the center of many relevant biological processes ranging from cellular differentiation to cancer invasion and metastasis. Microscopy techniques, such as electron microscopy (EM), super-resolution (SR) optical micros ...
EPFL2023Effects of thermal, mechanical, and electrostatic perturbations on lipid membrane hydration investigated by second harmonic imaging
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 ...
EPFL2023Significance of Receptor Mobility in Multivalent Binding on Lipid Membranes
Maartje Martina Cornelia Bastings, Diana Kornelia Morzy
Numerous key biological processes rely on the concept of multivalency, where ligands achieve stable binding only upon engaging multiple receptors. These processes, like viral entry or immune synapse formation, occur on the diffusive cellular membrane. One ...
WILEY-V C H VERLAG GMBH2022Water as a contrast agent for imaging interfacial structure and ion transport in giant vesicles
Hydrated lipid bilayer membranes and their asymmetry play a fundamental role in living cells by maintaining and regulating concentration gradients between cells, their environment, and their compartments. They achieve this not only through various channels ...
