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

open access: yes, 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 ...

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

open access: yesJournal 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

Study of macroscopic and microscopic properties of liposomes produced using microfluidic methods [PDF]

open access: yes, 2019
For the last decades, lipid vesicles or liposomes, vesicles formed by a bilayer of amphiphilic lipids, have been used as a toy model for studying the cell membrane and for applications in cosmetics and drug delivery.

Direct measurement of DNA-mediated adhesion between lipid bilayers

open access: yes, 2015
Multivalent interactions between deformable mesoscopic units are ubiquitous in biology, where membrane macromolecules mediate the interactions between neighbouring living cells and between cells and solid substrates.

Law of corresponding states for osmotic swelling of vesicles

open access: yes, 2012
As solute molecules permeate into a vesicle due to a concentration difference across its membrane, the vesicle swells through osmosis. The swelling can be divided into two stages: (a) an "ironing" stage, where the volume-to-area ratio of the vesicle ...
