Using computer simulations, we show that lipid membranes can mediate linear aggregation of spherical nanoparticles binding to it for a wide range of biologically relevant bending rigidities. This result is in net contrast with the isotropic aggregation of nanoparticles on fluid interfaces or the expected clustering of isotropic insertions in biological membranes. We present a phase diagram indicating where linear aggregation is expected and compute explicitly the free-energy barriers associated… 
Long-range attraction of particles adhered to lipid vesicles.
TLDR
This work studies the collective behavior of micrometric particles adhered to a lipid vesicle as a model system to study adsorption-mediated interactions and estimates the colloidal interactions using a maximum likelihood analysis of particle trajectories.
Membrane-mediated aggregation of anisotropically curved nanoparticles.
TLDR
This work studies the self-assembly of elongated curved nanoparticles on lipid vesicles based on molecular dynamics of a coarse-grained implicit-solvent model of self-assembled lipid membranes with a Langevin thermostat for systems with varying nanoparticle number densities, adhesion strength, and nanoparticle intrinsic curvature.
Self-assembly of nanoparticles adsorbed on fluid and elastic membranes
In this paper we review recent numerical and theoretical developments of particle self-assembly on fluid and elastic membranes and compare them to available experimental realizations. We discuss the
Influence of fluctuating membranes on self-assembly of patchy colloids.
A coarse-grained computational model is used to investigate the effect of a fluid membrane on patchy-particle assembly into biologically relevant structures motivated by viral cores and clathrin. For
Adhesion and Aggregation of Spherical Nanoparticles on Lipid Membranes.
TLDR
It is shown that the degree of wrapping of small NPs, by tensionless planar membranes, can increase continuously with the adhesion strength, however, thedegree of wrapping exhibits a discontinuity for large NPs or short interaction range.
Mechanism of membrane tube formation induced by adhesive nanocomponents.
TLDR
Numerical simulations of membrane tubulation driven by large colloidal particles find that tube formation is a result of the collective behavior of the particles adhering on the surface, and it occurs for binding strengths that are smaller than those required for budding.
Nanoparticle-induced permeability of lipid membranes.
Monte Carlo simulations using the bond fluctuation method with explicit solvent reveal the mechanism of enhanced permeability of lipid bilayers induced by the adsorption of nanoparticles with
Stability of membrane-induced self-assemblies of spherical nanoparticles.
The self-assembly of spherical nanoparticles, resulting from their adhesion on tensionless lipid membranes, is investigated through molecular dynamics simulations of a coarse-grained implicit-solvent
Size-dependent aggregation of hydrophobic nanoparticles in lipid membranes.
TLDR
It is found that the free energy of dimerization depends strongly on nanoparticle size: the smallest molecules (mimicking C60 fullerene) aggregate only weakly, the largest ones form large three-dimensional aggregates causing major deformations in the host membrane, and the intermediate-sized particles show a tendency to form linear aggregates.
Intake of silica nanoparticles by giant lipid vesicles: influence of particle size and thermodynamic membrane state
TLDR
Experiments on a massive uptake of silica nanoparticles by giant unilamellar lipid vesicles (GUVs) find that this uptake process depends on the size of the particles as well as on the thermodynamic state of the lipid membrane.

N-body study of anisotropic membrane inclusions: Membrane mediated interactions and ordered aggregation
TLDR
Long-range attractive interactions between inclusions are found to be sufficiently strong to induce aggregation, and Monte Carlo simulations show a transition from compact clusters to aggregation on lines or circles.
Network models of fluid, hexatic and polymerized membranes
The thermal behaviour of membranes - surfaces of nearly vanishing tension - depends strongly on their internal state, which can be either fluid, crystalline (or polymerized), or hexatic. Thermal
Surfactant-mediated two-dimensional crystallization of colloidal crystals
TLDR
This work has shown that the use of attractive Coulomb interaction between colloidal particles and surfactant structures offers a potential new route to self-assembly of ordered colloidal structures.
Simulations of Fluid Self-Avoiding Membranes
A model for fluid flexible self-avoiding membranes is introduced and investigated by Monte Carlo methods. Fluid athermal membranes consisting of N monomers exhibit crumpled shapes and their mean

We perform numerical simulations to study self-assembly of nanoparticles mediated by an elastic planar surface. We show how the nontrivial elastic response to deformations of these surfaces leads to
Long-Range Forces in Heterogeneous Fluid Membranes
We find a new long-range interaction between foreign inclusions (e.g. mobile proteins) in a fluid membrane which is mediated by the membrane itself. The interaction falls off as 1/R4, can be

Adhesion of cylindrical colloids to the surface of a membrane.
TLDR
It is shown that the free energy of two cylinders adhering to the same side of a membrane has two branches corresponding to shallow and deep wrapping and that the system of two cylindrical colloid systems can undergo a first-order phase transition between two membrane-mediated attractive states.
Particle self-assembly on soft elastic shells
We use numerical simulations to show how noninteracting hard particles binding to a deformable elastic shell may self-assemble into a variety of linear patterns. This is a result of the nontrivial
