Hybrid hydrogels for load-bearing implants
Load-bearing tissues such as articular cartilage or meniscus are not infallible. They might fail due to trauma, over-solicitations, or diseases, which could subsequently alter the mobility of the patient. Repairing these damaged tissues in a minimally inva ...
EPFL2021Silk granular hydrogels self-reinforced with regenerated silk fibroin fibers
Dominique Pioletti, Pierre-Etienne Bourban, Peyman Karami, Céline Samira Wyss, Adrien Julien Demongeot
Granular hydrogels with high stability, strength, and toughness are laborious to develop. Post-curing is often employed to bind microgels chemically and enhance mechanical properties. Here a unique strategy was investigated to maintain microgels together w ...
2021Hybrid granular hydrogels: combining composites and microgels for extended ranges of material properties
Dominique Pioletti, Pierre-Etienne Bourban, Peyman Karami, Céline Samira Wyss
Developing hydrogels with optimal properties for specific applications is challenging as most of these properties, such as toughness, stiffness, swelling or deformability, are interrelated. The improvement of one property usually comes at the cost of anoth ...
ROYAL SOC CHEMISTRY2020Cross-linkable polymer, hydrogel, and method of preparation thereof
Dominique Pioletti, Pierre-Etienne Bourban, Christophe Moser, Peyman Karami, Céline Samira Wyss
The invention relates to a cross-linkable polymer comprising a base polymer comprising functional groups at least some of which have been reacted with a first organic molecule comprising a cross-linkable unit and with a second organic molecule capable of b ...
2020Composite Double-Network Hydrogels To Improve Adhesion on Biological Surfaces
Dominique Pioletti, Pierre-Etienne Bourban, Christophe Moser, Peyman Karami, Andreas Schmocker, Azadeh Khoushabi, Céline Samira Wyss, Martin Broome
Despite the development of hydrogels with high mechanical properties, insufficient adhesion between these materials and biological surfaces significantly limits their use in the biomedical field. By controlling toughening processes, we designed a composite ...
2018Tailoring swelling to control softening mechanisms during cyclic loading of PEG/cellulose hydrogel composites
Dominique Pioletti, Pierre-Etienne Bourban, Baris Çaglar, Azadeh Khoushabi, Céline Samira Wyss
One of the novel approaches for discogenic lower back pain treatment is to permanently replace the core of the intervertebral disc, so-called Nucleus Pulposus, through minimally invasive surgery. Recently, we have proposed Poly(Ethylene Glycol) Dimethacryl ...
2018Cyclic loading of a cellulose/hydrogel composite increases its fracture strength
Dominique Pioletti, Pierre-Etienne Bourban, Peyman Karami, Céline Samira Wyss
The fracture properties of hydrogels which present similar characteristics to the Mullins effect is expected to decrease under repeated cyclic loading. Therefore, we assessed how cyclic loading affects the fracture behavior, the distribution of strain fiel ...
2018Finite element modelling of the bone-implant interface and experimental validation
Excessive interfacial micromotion endangers the implant primary stability by favoring the formation of a fibrous tissue layer at the bone-implant interface. It was recently proposed that implant micromotion induces fluid flow in the granulation tissue that ...
