Permeability of phospholipid membrane for small polar molecules determined from osmotic swelling of giant phospholipid vesicles

, 2012
A method for determining permeability of phospholipid bilayer based on the osmotic swelling of micrometer-sized giant unilamellar vesicles (GUVs) is presented as an alternative to the two established techniques, dynamic light scattering on liposome ...

Pepticombisomes: Biomimetic Vesicles Crafted From Recombinant Supercharged Polypeptides with Uniformly Distributed Side‐Chains

Advanced Science, Volume 12, Issue 15, April 17, 2025.
Pepticombisomes are biomimetic vesicles formed by elastin‐like supercharged unfolded polypeptides (SUPs) uniformly functionalized with anionic surfactants with lipid‐like hydrophobic tails. The molecular design of these supramolecular combs enables precise assembly into membranes with controlled thickness and flexibility.

Mutual Dependence between Membrane Phase Separation and Bacterial Division Protein Dynamics in Synthetic Cell Models

Angewandte Chemie International Edition, Volume 64, Issue 6, February 3, 2025.
We demonstrate the mutual dependence of membrane phase separation and bacterial division protein dynamics. By reconstituting Min and Fts proteins inside phase separated GUVs, we observe interesting mode selection for protein dynamics and change in the reaction kinetics.

Mass‐Guided Single‐Cell MALDI Imaging of Low‐Mass Metabolites Reveals Cellular Activation Markers

Advanced Science, Volume 12, Issue 5, February 3, 2025.
The PRISM‐MS workflow transforms single‐cell mass spectrometry imaging by allowing detailed analysis of low‐mass metabolites in large cell populations without metabolite degradation. By introducing novel concepts, e.g., giant unilamellar vesicles as ground truth, PRISM‐MS enables the identification of cell subpopulations and reveals complex metabolome ...

Selective Glycan Presentation in Liquid‐Ordered or ‐Disordered Membrane Phases and its Effect on Lectin Binding

Angewandte Chemie, Volume 137, Issue 2, January 10, 2025.
A panel of sequence‐defined, lipidated glycomimetics was synthesized and incorporated into phase‐separating GUVs to mimic cellular lipid rafts. Depending on the lipid anchor, the glycomimetics partition into either the Lo or Ld domain of the vesicles, enabling the construction of spatially defined glycocalyx models.

Influence of the preparation procedure on the electrochemical properties of Pani(DMcT-Cu ion)/carbon fiber composites

Journal of the Brazilian Chemical Society, 2003
The electrochemical properties of Pani(DMcT-Cu ion)/carbon fiber composites, obtained by electrochemical means, are analysed as a function of the preparation procedure and the different copper salts (CuCl2.2H2O or CuSO4) used as source of Cu2+ ions to be

A Molecular Rotor that Measures Dynamic Changes of Lipid Bilayer Viscosity Caused by Oxidative Stress

, 2016
Oxidation of cellular structures is typically an undesirable process that can be a hallmark of certain diseases. On the other hand, photooxidation is a necessary step of photodynamic therapy (PDT), a cancer treatment causing cell death upon light ...
