摘要
采用耗散粒子动力学模拟方法(DPD)研究了聚羧酸甜菜碱甲基丙烯酸酯(PCBMA)在不同浓度及pH下在水中的自组装与解组装情况,以及PCBMA与DNA的组装情况。模拟结果显示,不同浓度下,聚合物在水中依次形成球状、柱状、层状纳米粒子。pH下降时,DNA能被释放出来。
Using dissipative particle dynamics （DPD） simulation to study polycarboxy- betaine methacrylate （PCBMA） under different concentration and pH for self-assembly and solution of assembly under water, as well as the assembly of the PCBMA and DNA. According to the results, under different concentration, polymer form spherical, cylindrical and layered nanoparticles under water successfully. When pH falls, DNA can be released.
