PEG-detachable polyplexes were constructed for the first time via host-guest interactions between β-cyclodextrin and azobenzene. The polyplexes had excellent colloidal stability and competition stability. Moreover, the intracellular light-regulated dePEGylation facilitated DNA release and nuclear entry, thus resulting in efficient transfection.
首次通过β-环糊精和偶氮苯之间的主客体相互作用构建了可 PEG 去除的超分子聚合物。该超分子聚合物具有优异的胶体稳定性和竞争稳定性。此外,细胞内光调控的去 PEG 化促进了 DNA 的释放和核内进入,从而实现了高效转染。
