Brownian Dynamics simulation of binding kinetics of colloids

Despite a century of extensive research, a thorough model for determining the binding kinetics of even dilute colloidal particles under 3D flow concentrations has been elusive. This has been attributed to stiffness of governing convection-diffusion equation. Conducting Brownian dynamics simulations, we developed a robust theoretical framework for determining recognition and binding kinetics of particles for arbitrary inter-particle potentials, surface anisotropy, flow strength and with full consideration of hydrodynamic interactions (HI). We are currently extending our method to consider multibody effects. Here, a few results are provided, further details can be found in our published report.[1]

Agreement between our results and those in literature for particle trajectories under shear flow in the absence of Brownian motion:
