Nanotechnology operates with nanoparticles, which has a distinct border with the environment. Practice shows that the interaction forces of such particles should significantly exceed the forces of intermolecular interaction, and the interaction can be both attraction and repulsion. Such interactions between nanoparticles are explained below on the basis of the solution of Maxwell’s equations.


Nanotechnology operates with nanoparticles, which are an isolated solid-phase object that has a clearly defined boundary with the environment, the dimensions of which in all three dimensions are from 1 to 100 nm. Nanoparticles are close to those objects that are considering in supramolecular chemistry [1]. In this field of knowledge, the forces that bind individual molecules are considered. It is believed that intermolecular interaction consists of weak electromagnetic interactions. The energy of such interactions is inversely proportional to the sixth power of the distance between the molecules. Obviously, the interaction of nanoparticles with clear boundaries cannot be due to such forces [2-4].
The interaction of nanoparticles leads to one property that greatly interferes with their use - they can stick together [5-10]. This problem has to be solved in the production of ceramics and metallurgy. Obviously, this property is explained by the attraction of nanoparticles with different chemical compositions. But another property is also known, which can be explained by the repulsion of nanoparticles with different chemical compositions. It was shown that polycationic organic nanoparticles are shown to disrupt model biological membranes and living cell membranes at nanomolar concentrations [2]. Thus, the theory of interaction of nanoparticles should explain both the attraction and repulsion of nanoparticles, and the forces of such interaction should significantly exceed the forces of intermolecular interaction. The Maxwell equations for a capacitor with an alternating voltage in Cartesian coordinates were solved [3]. In the system of Cartesian coordinates x, y, z, t and in the SI system these equations have the form (1): (Table 1).

where Er, Eφ, Ez are the electric intensities, Hr, Hφ, Hz are the magnetic intensities? It was shown in [3] that this solution has the form:

where ex, ey, ez, hx, hy, hz are the constant amplitudes of the intensities, α, β, λ are constants, ω is the frequency. These quantities are related by the following equations:

hz = 0(8)

Table 1:

For given values of the parameters α, β, γ and frequency ω, the amplitudes of the intensities can be determined depending on ez. It follows from (14) that for ω = 0 the parameters α = β =γ = 0 i.e. the electromagnetic field cannot be static.

In (3) it is shown that energy with a density is stored in a capacitor

In this case, the density of energy fluxes along the coordinates are determined by the formulas


This means that the energy flux density along all axes varies in space and time, i.e. in a rectangular body there is a spatial standing wave. However, a stream of energy can pass through this body. Consider, for example, the face xoy at z = z1. The energy flux density (18) on this face is determined by function (19):

The energy flux is determined by the integral of this function on the entire xoy face:

The energy flux on the opposite face xoy at z = z2 is determined by the integral

From (18,20,21) we find the energy flux flowing through the capacitor along the 0z axis if (z2 < z1 ) :

It Follows from the Solution Found that

A. There is a combination of parameters in which the energy of the capacitor is not radiated. Consider, for example, a cube with parameters α = β = λ . If the length R of the cube’s half-edge is such that (α ⋅ R) = 0,sin(β ⋅ R) = 0,sin(γ ⋅ R) = 0 , then all the energy flux densities on the faces of the cube are zero-cm. [2-7]. In this case, there is no radiation.
B. An external energy flow can pass through the capacitor volume without changing its internal energy (as shown above). This flow is the active power that passes through the capacitor. C. The formulas are valid for any values of μ and ε.
Therefore, a capacitor with a certain energy and a standing wave in the capacitor volume can exist in a vacuum.
D. In the absence of external energy flows, the capacitor retains its integrity, since it does not radiate, and the energy density is preserved while maintaining the shape-see (15).
E. From p.p. 3 and 4 it follows that in some body, and even in a vacuum, a keeper of energy and information can exist. This is considered in detail in [3,4]. It is also shown there that a standing electromagnetic wave possessing the above properties can have a very diverse form.
F. Now suppose the nanoparticle stores the indicated electromagnetic wave. Such a single nanoparticle. In the absence of external energy flows, it retains its shape and electromagnetic energy.
G. Suppose a portion of external energy was expended to combine two nanoparticles. Then this portion of energy will go into the energy of the combined nanoparticle. We call this portion the binding energy of the conglomerate of two nanoparticles. Thus, the energy of a conglomerate of two particles is greater than the sum of the energies of these particles. Consequently, the conglomerate is more stable than individual particles, because for the destruction of the conglomerate it is necessary to first apply the binding energy. This can explain the adhesion of nanoparticles (as discussed above).

Obviously, the binding energy of particles for different materials is different. Now suppose that two particles of different materials come together and a conglomerate of these particles forms. If these materials do not mix, then conglomerate 21 should enter the environment of conglomerates 1 or 2. Obviously, it will enter the environment of conglomerates 1 if the binding energy of material 1 is higher than the binding energy of material 2. This can explain the above-mentioned fact that organic nanoparticles can destroy living cells.
