“…However, there is also a repulsive interaction in such systems, which is the cause of formation of the well-known Lennard-Jones potential. Its formation may be caused by the rather high nonlinear polarizabilities of the nanoparticles [34] or by the mode softening [35]. e model of interaction between two nanoparticles proposed in [34] takes into account the nanoparticles shapes and sizes, their linear and nonlinear polarizabilities, and selfconsistence of the local field.…”

Wide range of applications of nanoparticles causes the need to study their properties, and the influence of the interparticle interaction on the formation of the nanosystem properties is a well-known experimental phenomenon. The aim of this work is to study the influence of interparticle interactions on the properties of nanosystems theoretically. The influence of the interparticle interaction was simulated based on the near-field interaction potential and local field distribution. The local field distribution in the system was calculated using the Green function method and the concept of the effective susceptibility. The results show that interaction between nanoparticles can be neglected if the distance between them is bigger than the critical one. Expressions for evaluation of the efficiency of the interparticle coupling were proposed and compared with the existing experimental results. The results of the simulation are in good agreement with the measured values of the critical interparticle distance. The approach may be useful for simulation of interactions in the system of many nanoparticles and for engineering of nanostructures for different applications.

“…No new absorption peak was observed in the FTIR spectra after metal adsorption, while aside change in peak intensities, no other significant change was observed in XRD diffractograms of the samples. These reports suggest the exclusion of the formation of other compounds as a result of the interactions, thereby predicting the binding mechanism of Ni 2+ , Cr 3+ and Co 2+ ions as physical, occurring mainly via van der Walls interaction [61]. On the other hand, the involvement of ion exchange mechanism cannot be ruled out.…”

“…In this case, the addition to the internal energy of the particle caused by the dipole momentum of this particle will be lower than the energy of the chemical bonds in the material. Then, one can write the internal energies of the particles 'a' and 'b' as the expansion in a Taylor series over the dipole momentum P accurate within P 4 [19,20] , 4 1 1…”

Abstract.A new mechanism of interaction between two nanoparticles characterized by their dimensions and shape has been proposed. The mechanism is based on the local-field induced dipole momentum interaction with taking into account nonlinear polarizabilities of the particles. The dipole momentum induced in the particles has a fluctuating nature. The proposed mechanism of interparticle interaction leads to formation of both repulsive and attractive parts having the minimum at the distance between the particles close to their linear dimensions. The profile and strength of the potential depend both on dimensions and shapes of the particles as well as on their mutual orientation. Implementation of the discussed interaction conception to biology and medicine has been discussed.Keywords: nanoparticle, local-field enhancement, vacuum field fluctuations, antiviral activity.Manuscript received 27.08.12; revised version received 25.09.12; accepted for publication 17.10.12; published online 12.12.12.
