    • The shown curves correspond to certain values of those parameters and they are focused on highlighting the possibility for voltage induced adsorption-desorption of large nanoparticles, the effect necessary for our optical device. Specifically, we considered very large charges of nanoparticles (-1000e). Such values are not impossible, but so far have not been reported in the literature. Definitely, having the highest possible charge values has an advantage of a maximal response to potential variation, as is seen in Figure 2. Such strong coupling is needed to be able to move the particles in and out of the adsorption well with the electric field for the values of surface tension parameters used in our estimates.

Such strong coupling is needed to be able to move the particles in and out of the adsorption well with the electric field for the values of surface tension parameters used in our estimates. However, we must admit that, strictly speaking, we do not know those parameters, not only because of the well-known inaccuracy of measurements of the ITIES surface tension, but primarily because we deal here not with a pure silver surface, but a functionalized one. Indeed, the surface tension of silver/water and silver/oil interface will depend on the surface concentration of functional groups; it will also be affected by the concentrations of inorganic and organic electrolytes. These in the end will affect the nanoparticle/ITIES contact angle. Without specially performed measurements we have only vague knowledge of its possible value. It may well happen that the "capillary drive" of the nanoparticles to the interface will be much weaker than used in Figure 2. We then may not need such a large value of the charge of nanoparticles for the electric-filed controlled manipulation of their positions relative to the interface.

    • 26 Unfortunately, the multipole contributions to the optical response may increase not only with the radius of nanoparticles but with decrease of the distance between them. We are not aware of any theory for an optical response of a nanoparticle monolayer that includes the quadrupolar polarizability. Without a detailed theory it is difficult to assess how strong will be its effect in dense monolayers, and this is an interesting area for future research
