摘    要:通过分子动力学模拟,研究DNA/B-PDEAEA纳米颗粒的自组装过程。模拟结果表明,在自组装过程中静电相互作用是主要驱动力;在相同氮磷比的条件下,随着DNA碱基对数目的增加,更易于形成稳定的纳米颗粒。在相同碱基对数目的条件下,随着氮磷比的增加,更趋向于形成稳定的纳米颗粒。

关 键 词:DNA  自组装  分子动力学模拟

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.
