Characterization of the mesh size of hydrogels from swelling properties

Hydrogels are cross-linked, water-swollen polymer networks that are widely used as a biomaterial. The suitability of hydrogels as biomedical materials, especially as drug delivery systems depend on their bulk structure. The most important parameters used t ...

Polymer Brush Gradients Grafted from Plasma-Polymerized Surfaces

Harm-Anton Klok, Tugba Bilgiç Tune

A new method for generating a surface density gradient of polymer chains is presented. A substrate-independent polymer deposition technique was used to coat materials with a chemical gradient based on plasma copolymerization of 1,7-octadiene and allylamine ...

A toolbox of oligopeptide-modified polymers for tailored elastomers

Véronique Michaud, Holger Frauenrath, Joël Cugnoni, Marijana Mionic Ebersold, Ruben Anton Snellings, Emmanuel Croisier, Su Liang, Thomas Schweizer

Biomaterials are constructed from limited sets of building blocks but exhibit extraordinary and versatile properties, because hierarchical structure formation lets them employ identical supramolecular motifs for different purposes. Here we exert a similar ...

Maleimide-Functionalized Thiol Reactive Copolymer Brushes: Fabrication and Post-Polymerization Modification

Harm-Anton Klok, Tugba Bilgiç Tune

Polymer brushes that present side chain functional reactive groups are attractive platforms for the development of functional surface coatings. From the wide spectrum of possible postpolymerization modification reactions, thiol-based conjugation chemistrie ...

One-pot photoinduced synthesis of conductive polythiophene-epoxy network films

Federica Sordo, Marco Sangermano

In this paper, we describe a novel methodology for fabricating conductive epoxy-polythiophene network films by simultaneous photoinduced step-growth and cationic ring opening polymerization processes. For this purpose, formulations containing a bifunctiona ...

Charge transfer relaxation in donor–acceptor type conjugated materials

Ursula Röthlisberger, Natalie Renuka Banerji, Mariateresa Scarongella, Andrey Laktionov

The development of conjugated materials bearing electron-rich and electron-poor units along their backbone introduces new possibilities to control functionality for organic electronic applications through charge transfer character in ground and excited sta ...

Ruthenium-catalyzed Atom Transfer Radical Addition Reactions

Kay Severin

Certain ruthenium complexes are potent catalysts for atom transfer radical addition (ATRA) and cyclization (ATRC) reactions, in particular if they are used in conjunction with reducing agents such as magnesium. This short overview summarizes recent develop ...

Ruthenium-Catalyzed Sequential Enyne Cross-Metathesis/ATRA Reactions

Kay Severin, Euro Solari, Gregor Kiefer, Jesus Ruiz

Sequential enyne cross-metathesis reactions of arylalkynes with ethylene followed by atom transfer radical addition (ATRA) with ethyl dichloroacetate or dichloroacetonitrile provide 1,5-dichloropent-2-ene derivatives. The second-generation Grubbs alkyliden ...

Measuring the mesh size of hydrogels

Mohamadreza Nassajian Moghadam

Hydrogels are cross-linked, water-swollen polymer networks that are widely used as a biomaterial. Because of high amount of water, they are mechanically poor and soft. This aspect limits their applications. The suitability of hydrogels as biomedical materi ...

Squaric Acid Mediated Synthesis and Biological Activity of a Library of Linear and Hyperbranched Poly(Glycerol)-Protein Conjugates

Harm-Anton Klok, Frederik Roman Wurm

Polymer-protein conjugates generated from side chain functional synthetic polymers are attractive because they can be easily further modified with, for example, labeling groups or targeting ligands. The residue specific modification of proteins with side c ...
