Spontaneous formation of ordered micro-wrinkles on a thermosensitive resist
Jürgen Brugger, Giovanni Boero, Xia Liu, Ana Conde Rubio, Mohammadreza Rostami
Self-organizing patterns with micrometer-scale features are promising for applications in photonics and bioengineering. Their spontaneous formation reduces the number of required processing steps. Here, we report an approach to spontaneously form stochasti ...
2021Hierarchical porous structure
Dominique Pioletti, Pierre-Etienne Bourban, Matteo Gregorio Modesto Marascio
Cellular thermoplastic structures with hierarchical multi-scale porosity (preferably 1-300 µm micro-porosity to 0.3-10 mm macro-porosity) are produced from an integrated approach of 3D printing, preferably by Fused Deposition Modeling (FDM), and of supercr ...
2018Development of functionalized alginate-based hydrogels to reduce fibrosis in the transplantation of microencapsulated cells
Nowadays, the development of cell therapy relies mainly on the advances made toward cell microencapsulation which allows to evade the need for immunosuppression during cell transplantation. Among the materials considered for cell encapsulation, hydrogels d ...
EPFL2018Influence of Fluorinated Surfactant Composition on the Stability of Emulsion Drops
Esther Amstad, Gianluca Nicolas Etienne, Michael David Kessler
Aqueous drops of a well-defined size are often used as small containers for conducting chemical and biochemical reactions, cell assays and as templates to produce microparticles. To prevent their coalescence, they must be stabilized, for example, using sur ...
Wiley-Blackwell2016Stabilization of the Amorphous Structure of Spray-Dried Drug Nanoparticles
The bioavailability of hydrophobic drugs strongly increases if they are formulated as amorphous materials because the solubility of the amorphous phase is much higher than that of the crystal. Moreover, the stability of these particles against crystallizat ...
Amer Chemical Soc2016The microfluidic post-array device: high throughput production of single emulsion drops
We present a microfluidic device that enables high throughput production of relatively monodisperse emulsion drops while controlling the average size. The device consists of a two-dimensional array of regularly-spaced posts. Large drops of a highly polydis ...
2014Photopolymerizable hydrogels for implants: Monte-Carlo modeling and experimental in vitro validation
Dominique Pioletti, Pierre-Etienne Bourban, Christophe Moser, Andreas Schmocker, Azadeh Khoushabi
Photopolymerization is commonly used in a broad range of bioapplications, such as drug delivery, tissue engineering, and surgical implants, where liquid materials are injected and then hardened by means of llumination to create a solid polymer network. How ...
Spie-Soc Photo-Optical Instrumentation Engineers2014Compartmentalization of Gold Nanocrystals in Polymer Microparticles using Electrohydrodynamic Co-Jetting
Polymer particles with micro- and nanoscale anisotropy have received increasing interest for their ability to simultaneously present different physical- and chemical properties. In this communication, we demonstrate that gold nanocrystals (NCs) can be sele ...
2009Size-Selective Diffusion in Nanoporous but Flexible Membranes for Glucose Sensors
Peter Ryser, Eric Meurville, Antoine Barraud, Nao Takano
A series of nanoporous membranes prepared from polyethylene-block-polystyrene were applied for size-selective diffusion of glucose and albumin molecules. Millimeter-sized test cells for characterization of such molecular diffusions were designed assuming a ...
American Chemical Society2009Nanostructured titania coatings for drug-eluting medical implants
Medical implants delivering drugs are used to ensure efficient medication at body sites, at which the conventional administration of drugs is insufficient. The application of drug-delivery coatings is a beneficial concept for implants exposed to mechanical ...
