Get Price“Raft” Formation by Two‐Dimensional Self‐Assembly of Block
Block copolymers can form a broad range of self‐assembled aggregates. In solution, planar assemblies usually form closed structures such as vesicles; thus, free‐standing sheet formation can be challenging. While most polymer single crystals are planar, their growth usually occurs by uptake of individual chains.

Complex polymer architectures via RAFT polymerization
Reversible addition fragmentation chain transfer (RAFT) polymerization has made a huge impact in macromolecular design. The first block copolymers were described early on, followed by star polymers and then graft polymers. In the last five years, the types of architectures available have become more and more complex.

As a proof of concept we have been looking at conjugating single stranded oligonucleotides to a RAFT agent and then polymerising a hydrophilic monomer with the RAFT-Oligonucleotide agent. Many different methods of characterising these polymers are used to identify these new materials, one of which is polyacrylamide gel electrophoresis (PAGE).
