Abstract

The main properties of viruses (they replicate inside the cell of all type of life forms, from animals and plants to microorganisms; have the shape from simple helical and icosahedral forms to more complex structures; are surrounded by protective protein “coat”; have very small size equal to the one-hundredth the size of most bacteria) determine the properties of the physical process that may influence viruses. It is shown in this work that spin supercurrent may be such a process.

One of the methods of influencing viruses is to change their form, for example, to deform and even unwind their helical forms. The spin supercurrent is distinct from other physical processes, most notably, in that it transforms angular momentum and, consequently, as a result of its action a change in the form of interacting objects may take place.

As spin supercurrent may transform angular momentum, then for a change in the form of viruses the spin supercurrent must emerge between viruses and objects whose form is similar to the form of viruses. Such objects may be 3D nanoparticles (NPs), for example, fullerenes and dendrimers.

The two aspects of influence of NPs on viruses are considered in this work: targeted drug delivery and change in viruses’ form.
