Increase in anionic Fe₃O₄ nanoparticle-induced membrane poration and vesicle deformation due to membrane potential – an experimental study

Abstract

Membrane potential plays a significant role in various cellular processes while interacting with membrane active agents. So far, all the investigations of the interaction of nanoparticles (NPs) with lipid vesicles...

A review on the measurement of the bending rigidity of lipid membranes

“…Furthermore, reports suggest that sugar concentration can also influence bending rigidity. Considering the significance of membrane potential 176 and protein channels in cell physiology, alterations in these factors can disrupt normal cellular functioning and lead to various diseases. Therefore, future research opportunities are identified to investigate the impact of membrane potential and channel-forming proteins on bending rigidity.…”

Determination of pore edge tension from the kinetics of rupture of giant unilamellar vesicles using the Arrhenius equation: effects of sugar concentration, surface charge and cholesterol

“…If the pore fails to close, rupturing of cells or vesicles occurs. 4,5 It has been investigated that a pore can be induced in the membrane due to various reasons, such as applying external force using micropipettes, 6 electric field, 7–10 optical illumination, 11 binding of antimicrobial peptides, 12,13 pore-forming toxins, 14 nanoparticles, 15,16 etc. Among the known factors influencing pore formation and growth, pore edge tension, Γ (sometimes referred to as line tension), plays an important role in pore dynamics of the lipid bilayers.…”
