“…We hope that there are some bridges of our results to existing knowledge in the vast field of science studying aggregation phenomena in dilute systems. To this point it is worth to mention the very recent paper on electric field induced macroscopic two-dimensional cellular phase separation in a suspension of nanoparticles with very low volume fraction [38]. The key point of that work (similar to our results presented in this Section) is that the interaction is strongly enhanced in the external electric field.…”

The aim of this work is to revisit the phenomenological theory of the interaction between membrane inclusions, mediated by the membrane fluctuations. We consider the case where the inclusions are separated by distances larger than their characteristic size. Within our macroscopic approach a physical nature of such inclusions is not essential, however we have always in mind two prototypes of such inclusions: proteins and RNA macromolecules. Because the interaction is driven by the membrane fluctuations, and the coupling between inclusions and the membrane, it is possible to change the interaction potential by external actions affecting these factors. As an example of such external action we consider an electric field. Under external electric field (both dc or ac), we propose a new coupling mechanism between inclusions possessing dipole moments (as it is the case for most protein macromolecules) and the membrane. We found, quite unexpected and presumably for the first time, that the new coupling mechanism yields to giant enhancement of the pairwise potential of the inclusions. This result opens up a way to handle purposefully the interaction energy, and as well to test of the theory set forth in our article.

“…Finally, an additional ITO-coated slide, with no polymer coating, was placed into a second 3D-printed mounting and this assembly was combined with the first mounted slide to form a fluid cell. 25 The fluid cell is shown in an exploded-view in Fig. 1B and assembled in Fig.…”
