Depletion-induced interactions between colloids in colloid-polymer mixtures depend in range and strength on size, shape, and concentration of depletants. Crowding by colloids in turn affects shapes of polymer coils, such as biopolymers in biological cells. By simulating hard-sphere colloids and random-walk polymers, modeled as fluctuating ellipsoids, we compute depletion-induced potentials and polymer shape distributions. Comparing results with exact density-functional theory calculations… 
Depletion-induced forces and crowding in polymer-nanoparticle mixtures: Role of polymer shape fluctuations and penetrability.
It is shown that polymer depletion-induced interactions and crowding depend sensitively on polymer shapes and penetrability, with important implications for bulk thermodynamic phase behavior.
Influence of solvent quality on depletion potentials in colloid-polymer mixtures.
Monte Carlo simulation is applied to analyze the influence of solvent quality on depletion potentials in mixtures of hard-sphere colloids and nonadsorbing polymer coils, modeled as ellipsoids whose principal radii fluctuate according to random-walk statistics.
Influence of solvent quality on conformations of crowded polymers.
Comparison of results for polymers in good and theta solvents indicates that excluded-volume interactions between polymer segments significantly affect crowding, especially in the limit of crowders much smaller than polymers.
Computational Modeling of Polymer Crowding: Influence of Solvent Quality and Dimensionality on Conformations
The structure and function of polymers in confined environments, e.g., biopolymers in the cytoplasm, are affected by macromolecular crowding. To explore the influence of solvent quality and

It is shown that an effective monodisperse pair potential can be constructed that describes the many-body correlations reasonably well by convoluting the RC pair potential with the density-dependent emergent size distributions and using a mean effective diffusion constant.
Confined crowded polymers near attractive surfaces.
We present results from molecular dynamics simulations of a spherically confined neutral polymer in the presence of crowding particles, studying polymer shapes and conformations as a function of the
Enhancement of stratification of colloidal particles near a substrate induced by addition of non-adsorbing polymers
Abstract Polymers are widely mixed in colloidal dispersions to make better materials. It is important to understand the effects of the addition of polymers. In the present work, we studied micro
Swelling, structure, and phase stability of compressible microgels.
Using Monte Carlo simulation, this work model bulk suspensions of microgels that interact via Hertzian elastic interparticle forces and can expand or contract via trial moves that allow particles to change size in accordance with the Flory-Rehner free energy of cross-linked polymer gels.
Multi-particle collision dynamics for a coarse-grained model of soft colloids.
The effective monomer method works well for linear chains, while the PSC method provides very good results for stars, paving the way to extend MPCD treatments to complex macromolecular objects such as microgels or dendrimers and to work with soft colloids at finite concentrations.
Theoretical predictions of structures in dispersions containing charged colloidal particles and non-adsorbing polymers.
A theoretical model to describe structural effects on a specific system of charged colloidal polystyrene particles, upon the addition of non-adsorbing PEG polymers is developed, which predicts the occurrence of equilibrium clusters at high polymer concentrations, but low particle volume fractions and salt levels.


Polymer induced depletion potentials in polymer-colloid mixtures
The depletion interactions between two colloidal plates or between two colloidal spheres, induced by interacting polymers in a good solvent, are calculated theoretically and by computer simulations.
Unusual features of depletion interactions in soft polymer-based colloids mixed with linear homopolymers.
The influence of the addition of polymer chains on the effective interaction between star polymers, as a model for the depletion potential in ultrasoft mixtures, shows that for both hard sphere mixtures and colloid-nonadsorbing polymer mixtures the range of the depletion interaction increases with the size ratio.
Direct measurement of depletion potentials in mixtures of colloids and nonionic polymers
In colloidal suspensions containing a binary mixture of hard spheres depletion forces occur which substantially contribute to the interaction of the larger spheres among themselves and a wall,
Polymer crowding and shape distributions in polymer-nanoparticle mixtures.
With increased nanoparticle crowding, it is found that polymers become more compact (smaller, more spherical), in agreement with predictions of free-volume theory.
Influence of polymer-excluded volume on the phase-behavior of colloid-polymer mixtures.
This work determines the depletion-induced phase-behavior of hard-sphere colloids and interacting polymers by large-scale Monte Carlo simulations using very accurate coarse-graining techniques and shows that including excluded-volume interactions between polymers leads to qualitative differences in the phase diagrams.

We computed the phase-separation behavior and effective interactions of colloid-polymer mixtures in the "protein limit," where the polymer radius of gyration is much larger than the colloid radius.

Simulation and theory consistently predict that ideal polymers are compressed by nanoparticles, and that compressibility and penetrability stabilise nanoparticle-polymer mixtures.
