Equilibrium and Out-of-Equilibrium Adherence of Hydrogels against Polymer Brushes

Costantino Creton, Jennifer Mary Adrienne Alice Macron

At low pH, underwater adherence between poly(N,N-dimethylacrylamide) hydrogels and poly(acrylic acid) brushes is due to the formation of multiple hydrogen bonds. The effect of the key parameters controlling the formation of these interactions (contact time ...

Nano Fibrillated Cellulose Based Composite Hydrogels for an Injectable Intervertebral Disc Implant

Azadeh Khoushabi

Replacing the gel-like central part of the intervertebral disc (IVD), so-called nucleus pulposus (NP), via a minimally invasive surgery is one of the most recent approaches in the lower back pain treatments. An appropriate biomaterial for NP replacement (N ...

Photo-polymerization, swelling and mechanical properties of cellulose fibre reinforced poly(ethylene glycol) hydrogels

Dominique Pioletti, Pierre-Etienne Bourban, Andreas Schmocker, Azadeh Khoushabi

The application of hydrogels as load-bearing biomedical components is often limited by their mechanical properties. Often an attempt to improve a hydrogel's stiffness is accompanied by a loss of toughness and swelling properties. In this work, we show that ...

Improving hydrogels’ toughness by increasing the dissipative properties of their network

Dominique Pioletti, Mohamadreza Nassajian Moghadam

The weak mechanical performance and fragility of hydrogels limit their application as biomaterials for load bearing applications. The origin of this weakness has been explained by the low resistance to chains breakage composing the hydrogel and to the crac ...

Microscale patterning of hydrogel stiffness through light-triggered uncaging of thiols

Matthias Lütolf, Katarzyna Mosiewicz, Laura Kolb

Mammalian cell behavior is strongly influenced by physical and chemical cues originating from the extracellular matrix (ECM). In vivo, ECM signals are displayed in a spatiotemporally complex fashion, often composed as gradients and in concentration profile ...
