Study of the Interaction of a Novel Semi-Synthetic Peptide with Model Lipid Membranes
Membranes, 2020 Most linear peptides directly interact with membranes, but the mechanisms of interaction are far from being completely understood. Here, we present an investigation of the membrane interactions of a designed peptide containing a non-natural, synthetic ...

Microwave measurement of giant unilamellar vesicles in aqueous solution [PDF]
Scientific Reports, 2018 AbstractA microwave technique is demonstrated to measure floating giant unilamellar vesicle (GUV) membranes in a 25 μm wide and 18.8 μm high microfluidic channel. The measurement is conducted at 2.7 and 7.9 GHz, at which a split-ring resonator (SRR) operates at odd modes.

Light-Switchable Membrane Permeability in Giant Unilamellar Vesicles
Pharmaceutics, 2022 In this work, giant unilamellar vesicles (GUVs) were synthesized by blending the natural phospholipid 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine (POPC) with a photoswitchable amphiphile (1) that undergoes photoisomerization upon irradiation with UV-A (E to Z) and blue (Z to E) light.

Self‐Assembled Lipids as Soft Dielectrics
Advanced Functional Materials, EarlyView.Self‐assembled lipid bilayers serve as soft dielectric materials for ultrathin electronics. Using liquid‐metal parallel‐plate junctions, the capacitance and dielectric breakdown of dehydrated lipid films are characterized. Dielectric behavior is controlled by lipid molecular structure, cholesterol content, and assembly conditions, providing molecular ...

Formation of Giant Unilamellar Vesicles Assisted by Fluorinated Nanoparticles
Advanced Science, 2023 AbstractIn the quest to produce artificial cells, one key challenge that remains to be solved is the recreation of a complex cellular membrane. Among the existing models, giant unilamellar vesicles (GUVs) are particularly interesting due to their intrinsic compartmentalisation ability and their resemblance in size and shape to eukaryotic cells.
