On the basis of DNA self‐assembly, a thermal responsive polymer polypropylene oxide (PPO) is evenly inserted into a rigid 3D DNA network for the study of single molecular self‐collapsing process. At low temperature, PPO is hydrophilic and dispersed uniformly in the network; when elevating temperature, PPO becomes hydrophobic but can only collapse on itself because of the fixation and separation of DNA rigid network. The process has been characterized by rheological test and Small Angle X‐Ray Scattering test. It is also demonstrated that this self‐collapsing process is reversible and it is believed that this strategy could provide a new tool to study the nucleation‐growing process of block copolymers.

3D DNA网络中单分子聚环氧丙烷（PPO）的自折叠
在DNA自组装的基础上，将热响应聚合物聚环氧丙烷（PPO）均匀地插入到刚性3D DNA网络中，以研究单分子自折叠过程。在低温下，PPO是亲水性的，并且均匀地分散在网络中。当升高温度时，PPO变为疏水性，但由于DNA刚性网络的固定和分离而只能自身崩塌。该过程已通过流变测试和小角X射线散射测试进行了表征。还证明了这种自塌缩过程是可逆的，并且认为该策略可以为研究嵌段共聚物的成核生长过程提供新的工具。
