Cross-Reactive Alginate Derivatives for the Production of Dual Ionic−Covalent Hydrogel Microspheres Presenting Tunable Properties for Cell Microencapsulation

Sandrine Gerber, Aurélien Bornet, François Rémi Pierre Noverraz, Luca Szabó

The production of hydrogel micropsheres (MS) presenting physical, mechanical, and biological properties which can be modulated by their chemical composition is required to enlarge the panel of biomaterials for cell transplantation therapies. Functionalizat ...

Synthesis strategies to extend the variety of alginate-based hybrid hydrogels for cell microencapsulation

Sandrine Gerber, François Rémi Pierre Noverraz, Jutta Christine Wandrey, Solène Marcelle Françoise Marie Passemard, Luca Szabó

The production of hydrogel microspheres (MS) for cell immobilization, maintaining the favorable properties of alginate gels but presenting enhanced performance in terms of in vivo durability and physical properties, is desirable to extend the therapeutic p ...

Assessment Of The Dispersion Quality Of Refractive Index-Matched Nanodispersions

Véronique Michaud

Dispersion quality has a large influence on the resulting properties of filled polymers, hybrids and nanocomposites in general. Reducing the van der Waals forces and therefore, matching the refractive index between the filler and the matrix should improve ...

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 ...

Encapsulation of Huh-7 cells within alginate-poly(ethylene glycol) hybrid microspheres

Jutta Christine Wandrey, Redouan Mahou

Novel calcium alginate poly(ethylene glycol) hybrid microspheres (Ca-alg-PEG) were developed and evaluated as potentially suitable materials for cell microencapsulation. Grafting 5-13% of the backbone units of sodium alginate (Na-alg) with alpha-amine-omeg ...

Link between Alginate Reaction Front Propagation and General Reaction Diffusion Theory

Jürgen Brugger, Philippe Renaud, Thomas Michael Braschler, Kristopher Pataky, Ana Valero, Ludovica Colella

We provide a common theoretical framework reuniting specific models for the Ca2+-alginate system and general reaction diffusion theory along with experimental validation on a microfluidic chip. As a starting point, we use a set of nonlinear, partial differ ...

Nanofibrillated cellulose composite hydrogel for the replacement of the nucleus pulposus

Dominique Pioletti, Pierre-Etienne Bourban, Ana Borges de Couraça, Fabien Duc

The swelling and compressive mechanical behavior as well as the morphology and biocompatibility of composite hydrogels based on Tween® 20 trimethacrylate (T3), N-vinyl-2-pyrrolidone (NVP) and nanofibrillated cellulose (NFC) were assessed in the present stu ...

Alginate-Poly(ethylene glycol) Hybrid Microspheres with Adjustable Physical Properties

Jutta Christine Wandrey, Redouan Mahou

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 ...
