We demonstrate both theoretically and experimentally that gold NPs can be separated by density gradient centrifugation (DGC) according to their size. By analyzing the force balance in a centrifuge with a horizontal rotor, a model was developed that relates the sedimentation shift to the centrifugation time and can be used to predict the effect of separation …
