Transport of solid bodies along tubular membrane tethers.

PLoS ONE, 2019
We study the crucial role of membrane fluctuations in maintaining a narrow gap between a fluid membrane tube and an enclosed solid particle. Solvent flows can occur in this gap, hence giving rise to a finite particle mobility along the tube.

Diacetylene‐Functionalized Glycan Mimetics for Receptor‐Mediated Cluster Imprinting in Model Membranes

Macromolecular Rapid Communications, Volume 47, Issue 14, 20 July 2026.
Diacetylene‐containing glycan mimetics cluster upon selective lectin binding in GUVs. Subsequent irradiation leads to the formation of fluorescent polymer clusters, while non‐clustered glycan mimetics remain unaffected in the membrane. ABSTRACT The glycocalyx, a dense layer of glycoproteins and glycolipids on eukaryotic cells, is essential for cellular

Interaction of a Polyarginine Peptide with Membranes of Different Mechanical Properties

Biomolecules, 2019
The membrane translocation efficiency of cell penetrating peptides (CPPs) has been largely studied, and poly-arginines have been highlighted as particularly active CPPs, especially upon negatively charged membranes. Here we inquire about the influence of

Janus Polymeric Nanorods Inhibit human Amylin Oligomerization and Fibrillation for Potential Type 2 Diabetes Treatment

Small Science, Volume 6, Issue 7, July 2026.
We demonstrate that polymeric Janus nanorods (JNRs) delay both oligomerization and fibrillation of human islet amyloid polypeptide (hIAPP) through high‐affinity and sequence‐specific interactions. JNRs display a β‐hairpin mimetic ligand (LP2) on one face, enabling multivalent binding.

Freeze‐thaw Fusion Enables Multi‐component Delivery and Protein Synthesis in POPG‐containing Lipid Vesicles

ChemSystemsChem, Volume 8, Issue 4, July 2026.
POPG‐containing membranes reduce leakage during freeze–thaw fusion, enabling efficient multi‐component delivery and protein synthesis inside GUVs. ABSTRACT Fusion between giant unilamellar vesicles (GUVs) provides a simple way to deliver and mix biochemical substrates within compartments surrounded by phospholipid membrane.

Curvature‐Assisted Vesicle Explosion Under Light‐Induced Asymmetric Oxidation

Advanced Science
Exposure of cell membranes to reactive oxygen species can cause oxidation of membrane lipids. Oxidized lipids undergo drastic conformational changes, compromising the mechanical integrity of the membrane and causing cell death.

Induced phagocytic particle uptake into a giant unilamellar vesicle

Soft Matter, 2014
Phagocytosis, the uptake and ingestion of solid particles into living cells, is a central mechanism of our immune system. Due to the complexity of the uptake mechanism, the different forces involved in this process are only partly understood. Therefore the usage of a giant unilamellar vesicle (GUV) as the simplest biomimetic model for a cell allows one

Frequency-Dependent Electroformation of Giant Unilamellar Vesicles in 3D and 2D Microelectrode Systems

Micromachines, 2017
A giant unilamellar vesicle (GUV), with similar properties to cellular membrane, has been widely studied. Electroformation with its simplicity and accessibility has become the most common method for GUV production.

Structural and Functional Effects of the Interaction Between an Antimicrobial Peptide and Its Analogs with Model Bacterial and Erythrocyte Membranes

Biomolecules
Antimicrobial peptides (AMPs) are a primary defense against pathogens. Here, we examined the interaction of two BP100 analogs, R2R5-BP100 (where Arg substitutes Lys 2 and 5) and R2R5-BP100-A-NH-C16 (where an Ala and a C16 hydrocarbon chain are added to ...

Cytoplasmic abundant heat-soluble proteins from tardigrades protect synthetic cells under stress

Nature Communications
Cytoplasmic abundant heat-soluble (CAHS) proteins, a stress-responsive intrinsically disordered protein from tardigrades, have been discovered to form gel-like networks providing structural support during dehydration, thus enabling anhydrobiosis. However,
