Query: Bond formation kinetics affects self-assembly directed by
  ligand-receptor interactions   In this paper we study aggregation kinetics in systems of particles
functionalised by complementary linkers. Most of the coarse-grained models
currently employed to study large-scale self-assembly of these systems rely on
effective potentials between particles as calculated using equilibrium
statistical mechanics. In these approaches the kinetic aspects underlying the
formation of inter-particle linkages are neglected. We show how the rate at
which supramolecular linkages form drastically changes the self-assembly
pathway. In order to do this we develop a method that combines Brownian
dynamics simulations with a Gillespie algorithm accounting for the evolution of
inter-particle linkages. If compared with dynamics based on effective
potentials, an explicit description of inter-particle linkages results in
aggregates that in the early stages of self-assembly have a lower valency.
Relaxation towards equilibrium is hampered by the time required to break
existing linkages within one cluster and to reorient them toward free
particles. This effect is more important at low temperature and high particle
diffusion constant. Our results highlight the importance of including kinetic
rates into coarse-grained descriptions of ligand-receptor systems.
