  Trajectories of a polarizable species (atoms or molecules) in the vicinity of
a negatively charged nanoparticle (at a floating potential) are considered. The
atoms are pulled into regions of strong electric field by polarization forces.
The polarization increases the deposition rate of the atoms and molecules at
the nanoparticle. The effect of non-spherical shape of the nanoparticle is
investigated by the Monte Carlo method. The shape of the non-spherical
nanoparticle is approximated by an ellipsoid. Total deposition rate and its
flux density distribution along the nanoparticle surface are calculated. It is
shown that the flux density is not uniform along the surface. It is maximal at
the nanoparticle tips.
