Reverse Sequence Polymerization-Induced Self-Assembly in Aqueous Media. [PDF]

Angew Chem Int Ed Engl, 2022
AbstractWe report a new aqueous polymerization‐induced self‐assembly (PISA) formulation that enables the hydrophobic block to be prepared first when targeting diblock copolymer nano‐objects. This counter‐intuitive reverse sequence approach uses an ionic reversible addition–fragmentation chain transfer (RAFT) agent for the RAFT aqueous dispersion ...

DNA-Polymer Nanostructures by RAFT Polymerization and Polymerization-Induced Self-Assembly. [PDF]

Angew Chem Int Ed Engl, 2020
Abstract Nanostructures derived from amphiphilic DNA–polymer conjugates have emerged prominently due to their rich self‐assembly behavior; however, their synthesis is traditionally challenging. Here, we report a novel platform technology towards DNA–polymer nanostructures of various shapes by leveraging polymerization‐induced self ...
