When colloidal particles are introduced into nematic liquid crystals, topological defects are induced in the vicinity of the particle. Consequently, elastic attractive and repulsive forces act between particles and one- or two-dimensional structures are formed spontaneously. Self-assembled colloidal structures have the possibility to be applied to tunable photonic devices. In our experiment, we demonstrate an increase of the interparticle distance of an one-dimensional colloidal chain by trapping it on a splay-bend wall induced by an in-plane electric field. We measured how the interaction force between the colloidal particles changes with the increase of the applied electric field.
