Can LIGGGHTS be an alternative way for DPD and SRD in simulation of colloids dynamics?

Hello everybody
I am beginner with the LIGGGHTS and have a fundamental question.
What are the limitations to use LIGGGTHS for simulation of nano-particles in aqueous media? Is this software restricted only for granular microscopic particles or even applicable for simulation of mesoscopic colloids? For example, can it be an alternative for DPD (Dissipative particle dynamics) or SRD (Stochastic rotation dynamics) methods in simulating colloids sedimentation or aggregation?
