Light sensitive phenacyl crosslinked dextran hydrogels for controlled delivery

Autor: Tobias G. Brevé, Mike Filius, Tim Groeneveld, Rienk Eelkema, Stefan van der Griend, Antonia G. Denkova, Sven Weerdenburg

Stimuli-responsive soft materials enable controlled release of loaded drug molecules and biomolecules. Controlled release of potent chemotherapeutic or immunotherapeutic agent is crucial to reduce unwanted side effects. In an effort to develop contro

Photo cleavable thioacetal block copolymers for controlled release

Autor: Rienk Eelkema, Antonia G. Denkova, Yongjun Men, Tobias G. Brevé, Huanhuan Liu

Publikováno v: Polymer Chemistry
Polymer Chemistry, 12(25)

We present a new light cleavable polymer containing o-nitrobenzene thioacetal groups in the main chain. By conjugation to a PEG block, we synthesized block copolymers capable of forming nanoparticles in aqueous solution. We studied drug encapsulation

Gamma Radiation Induced Contraction of Alkyne Modified Polymer Hydrogels

Autor: Antonia G. Denkova, Huanhuan Liu, Rienk Eelkema, Tobias G. Brevé

Publikováno v: Macromolecular Materials and Engineering
Macromolecular Materials and Engineering, 307(3)

Gamma radiation triggered secondary crosslinking of dextran hydrogels leads to macroscopic hydrogel contraction. The authors use stable polymer hydrogels, prepared through azide-alkyne crosslinking, containing surplus alkyne groups. γ-irradiation of
