Polysaccharide Layer-by-Layer Coating for Polyimide-Based Neural Interfaces

Silvestro Micera

Implantable flexible neural interfaces (IfNIs) are capable of directly modulating signals of the central and peripheral nervous system by stimulating or recording the action potential. Despite outstanding results in acute experiments on animals and humans, ...

Light-induced assembly and disassembly of polymers with PdnL2n-type network junctions

Kay Severin, Cristian Pezzato, Cesare Berton, Rujin Li

Polymers containing PdnL2n complexes as network junctions were obtained by reaction of poly(ethylene glycol)-linked N-donor ligands with Pd2+. The addition of a metastable state photoacid renders the networks light sensitive, and gel–sol transitions can be ...

Hybrid hydrogels for load-bearing implants

Céline Samira Wyss

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 ...

Narrowband Optical Coupler Using Fano Interference in First Order Diffraction

Olivier Martin, Benjamin Gallinet, Giorgio Quaranta, Fabian Michael Lütolf

Light coupling in waveguides has been extensively investigated in a variety of contexts, from photonic integrated circuits to biosensing and near-eye displays for augmented reality. Here, narrowband diffraction is reported using a Fano interference effect ...

Instability of a thin viscous film flowing under an inclined substrate: steady patterns

François Gallaire, Gioele Mariano Nicolò Balestra, Pier Giuseppe Ledda, Gaëtan Pierre Clément Lerisson

The flow of a thin film coating the underside of an inclined substrate is studied. We measure experimentally spatial growth rates and compare them to the linear stability analysis of a flat film modelled by the lubrication equation. When forced by a statio ...

PEG/HA Hybrid Hydrogels for Biologically and Mechanically Tailorable Bone Marrow Organoids

Nicolas Antoine Vincent Broguiere, Martin Ehrbar, Queralt Vallmajó Martín

Bone marrow (BM) organoids provide powerful tools to study the vital interplay between the BM microenvironment and resident cells. Current biomaterials, however, are limited in terms of versatility for independently studying the biochemical and biophysical ...

Low-Defect Thiol-Michael Addition Hydrogels as Matrigel Substitutes for Epithelial Organoid Derivation

Matthias Lütolf, Nikolche Gjorevski, Saba Rezakhani

Due to their selective crosslinking chemistry and well-defined mechano-biochemical characteristics, hydrogels crosslinked by thiol-Michael addition reactions have garnered immense interest for 3D cell culture applications. These hydrogels are typically for ...

Porous granules by freeze granulation of Pickering emulsions stabilized with halloysite particles

Paul Bowen

Pickering emulsions stabilized with a natural silicate mineral, halloysite, were dried by freeze granulation in order to prepare porous granules. Different formulations were studied, by varying the pH of the suspension, the ionic strength and with the addi ...
