Gels formed from the interaction of lipid vesicles: Influence of charge in their structural and rheological properties

Susana Vilchez, researcher at NANBIOSIS U12. Nanostructured liquid characterization unit  of CIBER-BBN and IQAC-CSIC, is coauthor of an article recently published in the Journal of Molecular Liquids.

“This work – explains Susana Vilchez – shows how structural and viscoelastic properties of a lipid colloidal gel can be altered by varying the ratio of charged lipids in the dispersion. These findings corroborate that the eventual formation of the gel and the morphology of its network is governed by the repulsive potential of the particles instead of the molecular composition of their membranes. Thus, the right control of charge balance in the system may allow finding specific applications for such material, especially in the biomedical field due to its lipid composition”.

Rheological measurements have been performed by the Nanostructured Liquids Unit (U12) of the ICTS NANBIOSIS.
