Journal ArticleDOI
Poly(2-cyclopropyl-2-oxazoline): From Rate Acceleration by Cyclopropyl to Thermoresponsive Properties
Meta M. Bloksma,Meta M. Bloksma,Christine Weber,Igor Perevyazko,Anette Kuse,Anja Baumgärtel,Antje Vollrath,Richard Hoogenboom,Richard Hoogenboom,Ulrich S. Schubert,Ulrich S. Schubert +10 more
TL;DR: In this article, a microwave-assisted living cationic ring-opening polymerization of 2-cyclopropyl-2-oxazoline is reported, which is attributed to the electron withdrawing effect of the cyclopropyl group.
Journal ArticleDOI
Polyelectrolyte Complexes of DNA and Linear PEI: Formation, Composition and Properties
Igor Perevyazko,Marius Bauer,Georges M. Pavlov,Stephanie Hoeppener,Stephanie Schubert,Dagmar Fischer,Ulrich S. Schubert +6 more
TL;DR: In the present study, the complexation between linear 13.4 kDa poly(ethylene imine) (LPEI) and plasmid DNA was investigated and it was demonstrated that virtually all added PEI binds to the DNA at N/P < 2.5; further addition of PEI results in the appearance of a large amount of free PEI in solution.
Journal ArticleDOI
Characterization of poly(methyl methacrylate) nanoparticles prepared by nanoprecipitation using analytical ultracentrifugation, dynamic light scattering, and scanning electron microscopy
Igor Perevyazko,Antje Vollrath,Stephanie Hornig,Georges M. Pavlov,Georges M. Pavlov,Georges M. Pavlov,Ulrich S. Schubert,Ulrich S. Schubert +7 more
TL;DR: In this article, it was shown that the particle characteristics strongly depend on the chemical structure of the polymers and the way of preparation and therefore vary in the studied cases in the range of 6 < d w < 680 nm, whereas the polydispersity index d w/d n changes in a range of 1.02 to 1.40.
Journal ArticleDOI
Conformation parameters of linear macromolecules from velocity sedimentation and other hydrodynamic methods
TL;DR: The approaches to the problems of hydrodynamic methods, in particular analytical velocity ultracentrifugation, in the study of various types of linear macromolecule are discussed and the estimation of the frictional ratio obtained by Sedfit is discussed.
Journal ArticleDOI
Preparation, cellular internalization, and biocompatibility of highly fluorescent PMMA nanoparticles.
Antje Vollrath,David Pretzel,Christian Pietsch,Igor Perevyazko,Stephanie Schubert,George M. Pavlov,Ulrich S. Schubert +6 more
TL;DR: In vitro studies with mouse fibroblast cell line and differently sized NP showed a particle uptake into cells, and biocompatibility, non-toxicity, and hemocomp compatibility were demonstrated using a XTT assay, a live/dead staining, and an erythrocyte aggregation and hemolysis assay.
