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 ...

Matrix-Assisted Transplantation of Functional Beige Adipose Tissue

Riccardo Sinisi, Grigory Karateev

Novel, clinically relevant, approaches to shift energy balance are urgently needed to combat metabolic disorders such as obesity and diabetes. One promising approach has been the expansion of brown adipose tissues that express uncoupling protein (UCP) 1 an ...

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 ...

Microdrop Printing of Hydrogel Bioinks into 3D Tissue-Like Geometries

Jürgen Brugger, Philippe Renaud, Matthias Lütolf, Thomas Michael Braschler, Kristopher Pataky, Andrea Negro

An optimized 3D inkjet printing process is demonstrated for structuring alginate into a tissue-like microvasculature capable of supporting physiological flow rates. Optimizing the reaction at the single-droplet level enables wet hydrogel droplets to be sta ...
