In this presentation that will be especially aimed at non-chemists, I will introduce in a simple way the RAFT process, a new living/controlled radical polymerization that revolutionizes polymer synthesis.
This original polymerization technique has made possible what was impossible with conventional polymerization : to predict the size of a polymer chain, synthesize homogeneous polymer chains (with a narrow size distribution) and access to polymer architectures such as block copolymers from a wide variety of monomers and consequently with a wide variety of properties and applications.
Indeed, there is an increasing interest in such well-designed polymer architectures for many fields including biology and medicine. It is now possible to introduce different kinds of biomolecules precisely located along the polymer chain : saccharides, phospholipids, oligonucleotides, ligands like biotin, and also fluorophores. The resulting bioconjugates have many potential applications and the presentation will be illustrated by several examples from in vitro diagnostics.
