介绍软凝聚态物理重要研究对象之一,树枝形高分子在界面处行为的计算机模拟研究进展。纳米尺度的树枝形分子因其独特的聚合物和胶体两重性,在催化,载药,基因转染,材料等领域具有广泛应用,成为物理、化学、生物、材料科学广泛关注的一个研究方向。一方面,为了得到功能优良的树枝形大分子,必须剖析动力学特性以及它们自身的结构,另一方面,为了提高树枝形大分子在基因转染过程中的效率,必须了解树枝形大分子与细胞膜等在界面处的相互作用。所以,研究树枝形大分子本身结构的特点、在界面处的动力学行为已成为大家研究的热点。
The progress of computer simulation on the behavior of dendritic polymer at the interface is introduced. Nano-scale dendritic molecules have been widely used in many fields such as catalysis, drug loading, gene transfection, materials and so on due to their unique polymer and colloidal duality, and become a research focus in physics, chemistry, biology and materials science. On the one hand, in order to obtain dendrimer with excellent function, kinetic characteristics and their own structure must be analyzed. On the other hand, in order to improve the efficiency of dendrimer in gene transfection, it is necessary to understand the relationship between dendrimer and Cell membrane and other interactions at the interface. Therefore, the study of the structure of the dendrimer itself, the dynamic behavior at the interface has become a hot spot for everyone to study.
