Both osmotic pressure differences and micropipette aspiration increase miscibility transition temperatures in GUV lipid membranes, resolving prior conflicting tension-dependent reports.
- Why it matters: Tension’s effect on membrane liquid-liquid phase separation has been inconsistent across population-based osmotic experiments and single-vesicle aspiration or stretching measurements.
- What they did: The study applies osmotic pressure differences to vesicle populations and micropipette aspiration to single membranes, then compares transition temperatures while addressing conversion from osmolarity to tension via renormalization by dividing by the exterior osmolarity.
- The result: Hidden area, reduced thermal fluctuations, increased area per lipid, and pore formation are used to interpret shifts and time dependences, motivating unified theory and simulations across all tension regimes.
