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

Sandrine Gerber, Jutta Christine Wandrey, François Rémi Pierre Noverraz, Solène Marcelle Françoise Marie Passemard, Redouan Mahou, 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 ...

Compounds for functionalizing biomaterials

Sandrine Gerber, Françoise Borcard

The present invention provides compounds suitable for functionalizing biomaterials, in particular prosthetics and implant materials, functionalized biomaterials, and methods for synthesizing the compound. The compounds contain an anchoring group, a group f ...

Surface Modification of Biomaterials for Conjugation with Human Fetal Osteoblasts

Sandrine Gerber, Davide Städler, Françoise Borcard, Céline Marie Anne Journot, Phally Kong

Surface functionalization of hydroxyapatite (HA) and β-tricalcium phosphate (TCP) bioceramics with chemical ligands containing a pyrrogallol moiety was developed to improve the adhesion of bone cell precursors to the biomaterials. Fast and biocompatible co ...

Synthesis of bone-like structured foams

Sandrine Gerber, Françoise Borcard

Here we present a processing route to produce multi-structured ceramic foams based on the combination of particle-stabilized foams with polymeric sponges to produce positive and negative templating structures. Polyester sponges are infiltrated with freshly ...

Surface Functionalisation of Alumina Ceramic Foams with Organic Ligands

Sandrine Gerber, Vincent Laporte, Pascal Miéville, Françoise Borcard, Marc Anthony Caporini

Different anchoring groups have been studied with the aim of covalently binding organic linkers to the surface of alumina ceramic foams. The results suggested that a higher degree of functionalisation was achieved with a pyrogallol derivative - as compared ...

Chemical functionalization of bio-ceramics to enhance endothelial cells adhesion for tissue engineering

Sandrine Gerber, Davide Städler, Françoise Borcard

To control the selective adhesion of human endothelial cells and human serum proteins to bioceramics of different compositions, a multifunctional ligand containing a cyclic arginine-glycine-aspartate (RGD) peptide, a tetraethylene glycol spacer, and a gall ...

Functionalization of microstructured open-porous bio-ceramic scaffolds with human fetal cells

Sandrine Gerber, Corinne Scaletta, Davide Städler, Françoise Borcard

Bone substitute materials allowing trans-scaffold migration and in-scaffold survival of human bone-derived cells are mandatory for development of cell-engineered permanent implants to repair bone defects. In this study, we evaluated the influence on human ...

Covalent cell surface functionalization of human fetal osteoblasts for tissue engineering

Sandrine Gerber, Corinne Scaletta, Davide Städler, Aurélien Godinat, Françoise Borcard

The chemical functionalization of cell-surface proteins of human primary fetal bone cells with hydrophilic bioorthogonal intermediates was investigated. Toward this goal, chemical pathways were developed for click reaction-mediated coupling of alkyne deriv ...
