Reversible additionâfragmentation chain transfer (RAFT) polymerisation was used to produce a range of polymers terminated with an acridine group, which intercalates efficiently into dsDNA; the structure of the polymer determines the nature and strength of the interaction. Using a short 63 base pair dsDNA, discrete and well-defined DNAâpolymer hybrid nanoparticles were formed, which were characterised by dynamic light scattering, small-angle X-ray scattering and atomic force microscopy.
可逆加成-分裂链转移(RAFT)聚合用于生产一系列以
吖啶基团为终止基的聚合物,该基团能够有效地嵌入双链DNA中;聚合物的结构决定了其与DNA的相互作用性质和强度。使用短的63碱基对双链DNA,形成了离散且定义良好的DNA-聚合物杂化纳米颗粒,这些颗粒通过动态光散射、小角X射线散射和原子力显微镜进行了表征。
