Simulation of pulsatory liposome working using a linear approximation for transmembrane pore dynamics [PDF]

INCAS Bulletin
This paper presents an analytical solution of the differential equations describing the pulsatory liposome dynamics. We consider a unilamellar liposome filled with an aqueous solution of osmotic solute inserted in a hypotonic aqueous medium.

Mathematical Description of the Functioning of the Pulsatory Liposome [PDF]

INCAS Bulletin, 2023
We consider a liposome filled with the aqueous solution of an osmotic solute enclosed in a large water bath. Due to osmotic pressure, it works according to a sequence of cycles with two stages.

The pulsatory liposome works as a neuronal network (II) [PDF]

INCAS Bulletin
In this paper we consider a unilamellar liposome (lipid vesicle) filled with aqueous solution of an osmotic solute. This liposome is introduced in a hypotonic aqueous medium of large dimensions.

Analytical and numerical results for the pulsatory liposome [PDF]

INCAS Bulletin
In this work, we consider a special and interesting bionic object - the pulsatory liposome, which are an unilamellar liposome (lipid vesicle) filled with aqueous solution of osmotic solute.

EVOLUTION OF THE PULSATORY LIPOSOME BY ANALYTICAL METHODS

Annals of the Academy of Romanian Scientists. Series on Physics and Chemistry
This paper is a review for the analytical modelling of the biophysical engine represented by a liposome, filled with an osmotic solution, introduced into an aqueous medium. The processes leading to the appearance, evolution and dis- appearance of the liposome-pore are presented. Due to osmosis, the liposome grows to a maximum size that will lead to the

Cyclic Activity of an Osmotically Stressed Liposome in a Finite Hypotonic Environment. [PDF]

Langmuir, 2020
A lipid vesicle, or simply called a liposome, represents a synthetic compartment for the examination of transmembrane transport and signaling phenomena. Yet, a liposome is always subjected to size and shape fluctuations due to local and global imbalance ...

Pulsatory Liposome: A Possible Biotechnological Device

, 2023
A unilamellar liposome filled with an osmotic solution is introduced into a hypotonic aqueous environment. Because of the mechanical tension induced by the osmotic flow, the vesicle swells up to a critical size, when suddenly a transbilayer pore appears and the vesicle relaxing stage starts.
