陈道勇课题组在聚合物胶束与DNA的精确组装方面取得了新的进展。该课题组不久前报导了通过调控胶束与DNA间的相互作用,成功模拟了染色体初级结构的形成及其形成过程,并获得单分散的聚合物核壳结构纳米线(Kaka Zhang, Ming Jiang, and Daoyong Chen*, DNA/Polymeric Micelle Self-Assembly Mimicking Chromatin Compaction, Angew. Chem. Int. Ed. 2012, 51, 8744)。文章链接http://onlinelibrary.wiley.com/doi/10.1002/anie.201203483/abstract
最近,该课题组利用相似的原理,获得了在水中可良好分散并具有核壳结构的尺寸单分散的纳米环。并基于尺寸单分散纳米环与带相反电荷的小球作用,成功模拟纳米尺度的主客体相互作用,获得了有意义的结果。(Kaka Zhang, Han Miao, and Daoyong Chen*,Water-Soluble Monodisperse Core−Shell Nanorings: Their Tailorable Preparation and Interactions with Oppositely Charged Spheres of a Similar Diameter J. Am. Chem. Soc., 2014. 136, 15933)。文章链接:http://pubs.acs.org/doi/abs/10.1021/ja5099963
