Particle adhesion in model systems

Locally frozen defects in random sequential adsorption with diffusional relaxation

“…The depositing particles are represented by hard-core extended objects; they are not allowed to overlap. In monolayer deposition of colloidal particles and macromolecules [3][4][5][6] one can further assume that the adhesion process is irreversible. However, recent experiments on protein adhesion at surfaces [7][8] indicate that in biomolecular systems effects of surface relaxation, due to diffusional rearrangement of particles, are observable on time scales of the deposition process.…”

Dynamics of nonequilibrium deposition

“…Extensive theoretical study of such systems is relatively recent and it has been motivated by experiments where submicron-size colloid, polymer, and protein "particles" were the deposited objects; see [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] for a partial literature list, as well as other articles in this issue. It is usually assumed that the main mechanism by which particles "talk" to each other is exclusion effect due to their size.…”

Fiber deposition models in two and three spatial dimensions

“…There particles are deposited on a surface and either stick or are rejected according to certain exclusion rules, with a maximum coverage (the 'jamming limit') less than the close-packing limit. These types of models should be contrasted with the case of multilayer surface growth [1,6,7], where the main focus is in the asymptotic behavior of the growing surface in the continuum limit [9].…”

“…For some such systems, the inter-particle repulsion is strong enough to prevent multilayer growth [3]. However, the existence of dispersion forces can cause the particles to flocculate, or aggregate, and to precipitate out of the suspension [7,10]. For larger particles or clusters of particles, gravity often induces sedimentation out of the suspension.…”
