The Structural Dispersity of Oligoethylene Glycol-Containing Polymer Brushes Determines Their Interfacial Properties

Harm-Anton Klok, Alberto Ongaro, Irene Filipucci

Ought to their bioinert properties and facile synthesis, poly[(oligoethylene glycol)methacrylate]s (POEGMAs) have been raised as attractive alternatives to poly(ethylene glycols) (PEGs) in an array of (bio)material applications, especially when they are ap ...

Aqueous drops of a well-defined size are often used as small containers for conducting chemical and biochemical reactions, cell assays and as templates to produce microparticles. To prevent their coalescence, they must be stabilized, for example, using sur ...

Tuning the Properties of Hydrogel Microspheres by Adding Chemical Cross-linking Functionality to Sodium Alginate

Sandrine Gerber, François Rémi Pierre Noverraz, Jutta Christine Wandrey, Redouan Mahou, Solène Marcelle Françoise Marie Passemard, Françoise Borcard, Virginia Crivelli, Léo Bühler

Two novel types of hydrogel microspheres (MS) are presented. First, one-component microspheres (1-comMS) were produced from sodium alginate (Na-alg) equipped with thiolfunctionalized hydroxyl groups. The functionalization pathway included the conversion of ...

Alginate-Poly(ethylene glycol) Hybrid Microspheres for Primary Cell Microencapsulation

Jutta Christine Wandrey, Redouan Mahou

The progress of medical therapies, which rely on the transplantation of microencapsulated living cells, depends on the quality of the encapsulating material. Such material has to be biocompatible, and the microencapsulation process must be simple and not h ...

Influence Of Processing And Storage On The Shear Thickening Properties Of Highly Concentrated Monodisperse Silica Particles In Polyethylene Glycol

Véronique Michaud, Mathieu Soutrenon

The shear thickening behavior of concentrated suspensions can be exploited to dissipate energy during impact or shear loading. To preserve the consistency of the thickening behavior in practical applications, particle concentration, and dispersion should b ...

Hybrid Polymer Foams for Osteochondral Tissue Engineering

Matthieu Cuénoud

Articular cartilage is a soft tissue that covers the ends of articulating bones, and is essential for maintaining joint motion, i.e. translation and rotation between the bones. Articular cartilage nevertheless has a limited capacity for self-repair, and ca ...

EPFL2012

The lower critical solution temperature (LCST) behavior of novel poly(ethylene glycol) (PEG)-based copolymers bearing multiple functional groups, obtained by anionic ring-opening (co)polymerization (AROP), has been investigated. Variable comonomer ratios o ...

Arginine-Specific Modification of Proteins with Polyethylene Glycol

Harm-Anton Klok, Marc Gauthier

In this study, the residue-selective modification of proteins with polymers at arginine residues is reported. The difficulty in modifying arginine residues lies in the fact that they are less reactive than lysine residues. Consequently, typical chemo-selec ...

A one-step extrusion process under physiological conditions yielded calcium alginate-poly-(ethylene glycol) hybrid microspheres (Alg-PEG-M), for which the physical properties were adjustable by the macromolecular characteristics of the components, their co ...
