A Monte Carlo simulation scheme was used for the stabilization of neutral colloidal microspheres by means of highly charged nanoparticles. It was found that small nanoparticle concentration induce an effective repulsion that prevents gelation caused by the intrinsic van der Walls attraction between colloids. Colloidal nanoparticle size asymmetry and nanoparticle charge was used to manipulate the effective interactions. The results show that the effective interaction is independent of the intrinsic van der Waals attraction.
