Abstract: The self-assemble processes of DNA/B-PDEAEA nanoparticles are investigated by means of molecular dynamics simulations. The simulation results show that the electrostatic interaction force is the main driving force for the self-assembly process. At the same N/P ratio,stable nanoparticles form easier when the number of DNA base pairs is larger. With the same number of base pairs, stable nanoparticles form easier at larger N/P ratio.

Key words: DNA, self-assembly, molecular dynamics simulation
