  In our previous publication (Ref. 1) we have shown that the data for the
normalized diffusion coefficient of the polymers, $D_p/D_{p0}$, falls on a
master curve when plotted as a function of $h/\lambda_d$, where $h$ is the mean
interparticle distance and $\lambda_d$ is a dynamic length scale. In the
present note we show that also the normalized diffusion coefficient of the
nanoparticles, $D_N/D_{N0}$, collapses on a master curve when plotted as a
function of $h/R_h$, where $R_h$ is the hydrodynamic radius of the
nanoparticles.
