The working of a pulsatory liposome

Journal of Theoretical Biology, 2008
Under positive osmotic stress, a greater lipid vesicle swells to a critical diameter, when suddenly a transbilayer pore appears and grows to a maximum radius, then decreases and finally disappears. An amount of liquid was leaked out through the pore and the vesicle returns to the initial state and can start another cycle.

A mathematical investigation on the active substance pulsatory release from a solution-charged liposome

BioSystems, 2019
We adopt a model in which the time evolution of a solution-charged liposome with selective permeability is seen as a sequence of two-stage cycles. In the first stage the lipid vesicle with a certain input concentration of the active substance is swelling up in an osmotic process until it reaches a size that one pore is formed on its surface. The second

Analytical Modeling of the Functioning of the Pulsatory Liposome

Romanian Journal of Physics
In this paper the analytical solutions of the differential equations are presented. These equations describe the pulsatory liposome dynamics. We consider a unilamellar liposome filled with an aqueous solution of osmotic solute inserted in a hypotonic aqueous medium. Due to the osmosis process the liposome has a cyclic evolution.

AN ANALYTICAL APPROACH FOR THE PULSATORY LIPOSOME IN THE PORE RADIUS HYPOTHESIS

Revue roumaine de mathématiques pures et appliquées
One considers a unilamellar liposome filled with an aqueous solution of an osmotic solute. This liposome is introduced into an aqueous medium. Due to the osmosis process, the lipid vesicle swells up to a maximum size, when a transbilayer pore suddenly appears. Part of the internal solution leaks through this pore.
