Wireless Bioelectronic Modulation of Membrane Potential in Glioblastoma Using Carbon Nanotube Porins

open access: yesAdvanced Science, EarlyView.
A schematic illustrating glioblastoma cell membrane modulation using carbon nanotube porins (CNTPs) and an applied voltage. CNTPs enable ion flux leading to changes in membrane potential. This figure summarizes the concept of bioelectronic control of cell membrane voltage.

GUV preparation and imaging: Minimizing artifacts

open access: yesBiochimica et Biophysica Acta (BBA) - Biomembranes, 2010
The components of biological membranes are present in a physical mixture. The nonrandom ways that the molecules of lipids and proteins mix together can strongly influence the association of proteins with each other, and the chemical reactions that occur in the membrane, or that are mediated by the membrane.

Membrane‐Mediated Force Transduction Drives Stick‐Slip Motion of Lipid Vesicles

open access: yesAdvanced Science, EarlyView.
A rotating magnetic field actuates a ferromagnetic particle inside a lipid vesicle, generating internal flows that induce stick‐slip propulsion near a surface. Membrane properties—elasticity, excess area, and phase behavior—modulate this motion by shaping stress dissipation and force transduction.

Analysis of the shape fluctuations of reconstituted membranes using GUVs made from lipid extracts of invertebrates

open access: yesBiology Open, 2013
Summary Changes in the physical properties of the lipid matrix of cell membranes have repeatedly been proposed to underlie stresses associated with e.g. drought, cold and xenobiotics.

Low-cost equipment for electroformation of Giant Unilamellar Vesicles

open access: yesHardwareX, 2018
Giant Unilamellar Vesicles (GUVs) constitute a very useful model for biomembranes. They are usually generated by electroformation using sinusoidal potential waves applied between two platinum electrodes or electrodes composed of glasses covered by indium

A Note on Vestigial Osmotic Pressure

open access: yesMembranes, 2023
Recent experiments have indicated that at least a part of the osmotic pressure across the giant unilamellar vesicle (GUV) membrane was balanced by the rapid formation of the monodisperse daughter vesicles inside the GUVs through an endocytosis-like ...

Taming membranes: functional immobilization of biological membranes in hydrogels. [PDF]

open access: yesPLoS ONE, 2011
Single molecule studies on membrane proteins embedded in their native environment are hampered by the intrinsic difficulty of immobilizing elastic and sensitive biological membranes without interfering with protein activity.

Domain formation in membranes with quenched protein obstacles: Lateral heterogeneity and the connection to universality classes

open access: yes, 2010
We show that lateral fluidity in membranes containing quenched protein obstacles belongs to the universality class of the two-dimensional random-field Ising model.

Charge-induced phase separation in lipid membranes [PDF]

open access: yes, 2014
The phase separation in lipid bilayers that include negatively charged lipids is examined experimentally. We observed phase-separated structures and determined the membrane miscibility temperatures in several binary and ternary lipid mixtures of ...

Freeze-thaw cycles induce content exchange between cell-sized lipid vesicles

open access: yesNew Journal of Physics, 2018
Early protocells are commonly assumed to consist of an amphiphilic membrane enclosing an RNA-based self-replicating genetic system and a primitive metabolism without protein enzymes.
