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 ...

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 ...

2D MoS2 Nanopores: Wafer-scale Fabrication and Monolayer Stability for Long-term Single-Molecule Sensing

Mukeshchand Thakur

Biologically inspired solid-state nanopores are artificial openings or apertures in thin membranes similar to natural protein ion channels in a lipid bilayer of cell membranes. In solid-state nanopores, a thin insulating membrane with single or multiple po ...

Article Structure and functionality of a multimeric human COQ7:COQ9 complex

Matteo Dal Peraro, Luciano Andres Abriata

Coenzyme Q (CoQ) is a redox-active lipid essential for core metabolic pathways and antioxidant defense. CoQ is synthesized upon the mitochondrial inner membrane by an ill-defined "complex Q" metabolon. Here, we present structure-function analyses of a lipi ...

Water as a contrast agent for imaging interfacial structure and ion transport in giant vesicles

David Roesel

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 ...

Ion-bridges and lipids drive aggregation of same-charge nanoparticles on lipid membranes

Francesco Stellacci, Zekiye Pelin Güven, Giulia Rossi

The control of the aggregation of biomedical nanoparticles (NP) in physiological conditions is crucial as clustering may change completely the way they interact with the biological environment. Here we show that Au nanoparticles, functionalized by an anion ...
