Query: Can mass change the diffusion coefficient of DNA-coated colloids?   Inertia does not generally affect the long time diffusion of passive
overdamped particles in fluids. Yet we have discovered a surprising property of
particles coated with ligands, that bind reversibly to surface receptors --
  heavy particles diffuse more slowly than light ones of the same size. We show
this by simulation and by deriving an analytic formula for the mass-dependent
diffusion coefficient in the overdamped limit. We estimate the magnitude of
this effect for a range of biophysical ligand-receptor systems, and find it is
potentially observable for micronscale DNA-coated colloids.
