Abstract

<jats:title>Abstract</jats:title> <jats:p>Giant vesicles (GVs) comprising zwitterionic and anionic phospholipids (DOPC and POPG, respectively) at a molar ratio of 90:10 formed a sparse network of aggregates that dissociated into isolated GVs reversibly depending on the pH of the dispersion (pH range, 7.0–2.5). This reversibility was due to the fluctuations in the composition of as-grown GVs.</jats:p>
