I’m interested in exploring the properties of biologically relevant monolayers that present phase coexistence, characterized by domains formed by lipids in an ordered phase state dispersed in a continuous, disordered phase. By means of Brownian dynamics simulations, optical microscopy, and Langmuir balance, I have been studying inter-domain interactions, size polydispersity and other parameters that influence the structural and dynamical properties of the monolayer.

Domain size polydispersity effects on the structural and dynamical properties in lipid monolayers with phase coexistence

In lipid monolayers with phase coexistence, domains of the liquid-condensed phase always present size polydispersity. However, very few theoretical works consider size distribution effects on the monolayer properties. By means of Brownian dynamics simulations, we study the radial distribution function, the average mean square displacement and the average time-dependent self-diffusion coefficient of lipid monolayers with normal distributed size domains.

Dipolar interactions between domains in lipid monolayers at the air-water interface

A great variety of biologically relevant monolayers present phase coexistence characterized by domains formed by lipids in an ordered phase state dispersed in a continuous, disordered phase. From the difference in surface densities between these phases, inter–domain dipolar interactions arise. In this work, we propose a novel way of estimating the dipolar repulsion using a passive method based on the comparison of the pair correlation function obtained from experiments with that obtained from Brownian dynamics simulations of a model system.
