Does someone know how to determine the binding speed of $\ce{Fe3O4}$ nanoparticles coated with the alkyl chain of hexadecyltrimethoxysilane to microparticles in water? I know that a precise answer is difficult, but does someone know at least an estimate of the time needed for the nanoparticles to bind?
