Note: The effect of viscosity on the rate of diffusion-limited association of nanoparticles

Journal article, 2015

A study is conducted to investigate the effect of viscosity on the rate of diffusion-limited association of nanoparticles. The study focuses on the diffusion-limited association of suspended nanoparticles, to keep the analysis mathematically transparent. It is demonstrated that the reduction of association rate constant as compared with the definition in another equation is physically related to hydrodynamic slowdown of the particle mobility in the contact region.
