We have investigated coupling between two internal order of the complex fluid mixture, which consists of the lyotropic liquid crystal and the latex colloidal particles. When the diameter of the doped latex particles is comparable to the microscopic characteristic length of the liquid crystalline order, defects of the liquid crystals are excited around the latex particles. This elastic cotupling between the liquid crystalline order and the doped particles could produce the new type of the long-range attractive interparticle interaction. In other words, this interaction can be transmitted between particles by the microscopic distortion of background liquid crystalline order. It is much characteristic that this interparticle interaction have intrinsically long-range nature because of its elastic origin. For this reason, these types of long-range force are much important to construct and maintain the mezoscopic supramolecular system, such as biological systems, because the short range intermolecular interaction can play no role between quite large molecular assemblies or macromolecules.
