Computer Simulation of Biomolecules Around Metallic Nanoparticle for Biomolecular Electronics

Abstract

In this research we investigate interactions of alanine molecules and gold nanoparticles using computer simulation method. The adsorption of organic molecules on gold nanoparticles is shown as a function of molecules concentration for two nanoparticle sizes. As a result of provided studies we showed that by controlling the size of nanoparticles and the concentration of biomolecules, it is possible to regulate the aggregation of biological molecules and their adsorption on metallic nanoparticles.
