  In this Letter we further develop the proposed approach of optical
manipulation based on the interactions of non-linear optical effects with
nanoparticles. The interaction of the dissipative optical solitons with
nanoparticles is studied numerically. It is shown that the attraction of the
nanoparticles to the solitons can result in the formation of a stable bound
state of the solitons and the nanoparticles. The collision of the solitons with
different numbers of trapped particles is studied, and it is shown that the
collision of the solitons can result in releasing or redistributing the
nanoparticles between the solitons. It is demonstrated that the particle
mediated interaction between the solitons can affect their dynamics
significantly. The reported effects can be successfully used for optical
manipulation of nanoparticles and pave a way for efficient control over their
dynamics on nanoscale.
