Abstract

Using Monte-Carlo simulation, the modeling of the process for metallizing DNA fragment in an aqueous solution via the templating of gold nanoparticles has been carried out. The additive effect of the electrostatic interaction between the negative charges of the phosphate groups of DNA molecule and nanoparticles polarized in the intrinsic electric field of the template, and the short-range attraction between gold nanoparticles leads to the self-assembly of metalloorganic nanoaggregate. No special functionalization of the surface of the nanoparticles is supposed to be performed. The question of how the size of the nanoparticles influence the self-assembly of a nanoaggregate is treated. The assembly of a quasi-continuous metallic covering is shown can be templated.
