Surface-Initiated Controlled Radical Polymerization: State-of-the-Art, Opportunities, and Challenges in Surface and Interface Engineering with Polymer Brushes

Harm-Anton Klok, Jian Wang, Piotr Mocny, John Moraes, Justin Orazio Zoppe, Nariye Cavusoglu Ataman

The generation of polymer brushes by surface-initiated controlled radical polymerization (SI-CRP) techniques has become a powerful approach to tailor the chemical and physical properties of interfaces and has given rise to great advances in surface and int ...

Influence of Block versus Random Monomer Distribution on the Cellular Uptake of Hydrophilic Copolymers

Harm-Anton Klok, John Moraes, Muriel Blum, Raoul Peltier

The use of polymers has revolutionized the field of drug delivery in the past two decades. Properties such as polymer size, charge, hydrophilicity, or branching have all been shown to play an important role in the cellular internalization of polymeric syst ...

Avoiding compositional drift during the RAFT copolymerization of N-(2-hydroxypropyl)methacrylamide and N-acryloxysuccinimide: towards uniform platforms for post-polymerization modification

Harm-Anton Klok, John Moraes, Hedi Ketari, Ioana-Maria Simionca

Controlled radical polymerization techniques such as RAFT allow fine control over polymer molecular weight and architecture. These techniques, however, do not eliminate compositional drifts in copolymerizations, which are the consequence of differences in ...
