Influence of Salt on the Formation and Separation of Droplet Interface Bilayers

Phospholipid bilayers are a major component of the cell membrane that is in contact with physiological electrolyte solutions including salt ions. The effect on phospholipid bilayer mechanics an active research area due to its implications for cellular function and viability. In this manuscript we utilize droplet interface bilayers(DIBs), formed artificially between two aqueous droplets, unravel formation separation combination experiments numerical modelling under effects K$^+$, Na$^+$, Li$^+$, Ca$^{2+}$ Mg$^{2+}$. Initially, measured interfacial tension complex viscosity lipid monolayers at flat oil-aqueous show both properties sensitive concentration, ion size valency. Subsequently, DIB rates characteristic velocity scales ratio viscosity. Next, subjected system step strain by separating drops stepwise manner. By tracking evolution angle radius, influences decay angle, radius corresponding relaxation time. Finally, explain observed means mathematical model comprising Young-Laplace equation equation.
