Simulation and Theory of Antibody Binding to Crowded Antigen-Covered Surfaces

Paolo De Los Rios, Giuseppe Foffi, Francesco Piazza

In this paper we introduce a fully flexible coarse-grained model of immunoglobulin G (IgG) antibodies parametrized directly on cryo-EM data and simulate the binding dynamics of many IgGs to antigens adsorbed on a surface at increasing densities. Moreover, ...

Memory effects in schematic models of glasses subjected to oscillatory deformation

Giuseppe Foffi, Davide Fiocco

We consider two schematic models of glasses subjected to oscillatory shear deformation, motivated by the observations, in computer simulations of a model glass, of a nonequilibrium transition from a localized to a diffusive regime as the shear amplitude is ...

Hard sphere-like glass transition in eye lens alpha-crystallin solutions

Nicolas Dorsaz, Giuseppe Foffi

We study the equilibrium liquid structure and dynamics of dilute and concentrated bovine eye lens alpha-crystallin solutions, using small-angle X-ray scattering, static and dynamic light scattering, viscometry, molecular dynamics simulations, and mode-coup ...

Partial slip at fluid-solid boundaries by multiparticle collision dynamics simulations

Giuseppe Foffi, Maxim Belushkin, Samuel Hanot

The understanding of the exact boundary conditions at the interface between a solid and a fluid is becoming increasingly important, as the limitations of the no-slip boundary condition are becoming apparent, especially in micro- and nanofluidics applicatio ...

Arrested demixing opens route to bigels

Nicolas Dorsaz, Francesco Varrato, Giuseppe Foffi, Maxim Belushkin

Understanding and, ultimately, controlling the properties of amorphous materials is one of the key goals of material science. Among the different amorphous structures, a very important role is played by colloidal gels. It has been only recently understood ...

Role of fluid-density correlations in hydrodynamics: a multiparticle collision dynamics simulation study

Giuseppe Foffi, Maxim Belushkin

Hydrodynamic interactions play a pivotal role in the dynamical behaviour of mesoscale systems such as colloidal suspensions, yet isolating their contribution from other effects remains a key challenge. Hydrodynamic correlations within a fluid are a consequ ...

Backtracking of Colloids: A Multiparticle Collision Dynamics Simulation Study

Giuseppe Foffi, Maxim Belushkin

The role of sound in the dynamics of mesoscale systems is typically neglected, since frequently the associated time scales are much smaller than all the other time scales of interest. However, for sufficiently small objects embedded in a solvent with a suf ...

Phase separation in binary eye lens protein mixtures

Nicolas Dorsaz, Giuseppe Foffi

Liquid–liquid phase separation occurs in young mammalian eye lenses and in concentrated solutions of isolated eye lens proteins, and has been linked to some forms of cataract. Here we study theoretically the protein compositions and cloud temperatures of t ...
