Pad printing 1-10 mm thick elastomer membranes for DEAs

Herbert Shea, Samuel Rosset, Alexandre Poulin

We present a technique for stamping patterned silicone elastomer membranes with thicknesses ranging from 1 to 10 um. Silicone elastomers are becoming the material of choice for dielectric elastomer transducers. The variety of readily available materials, t ...

In situ synthesis and simulation of polydisperse amphiphilic membranes

Lida Kanari, Julian Charles Shillcock, Liesbeth Maria L Vanherpe, Guy Antoine Atenekeng Kahou, Juan Pablo Palacios

The field of coarse-grained simulations of biopolymers and membranes has grown rapidly in recent years. Industrial groups manufacture and use polymers in fields as diverse as chemicals processing and personal care products, while academic researchers are i ...

Soft compartmentalization: Combining droplet-based microfluidics with freely accessible cells

Christoph Merten

Droplet‐based microfluidics allows the generation and manipulation of many independent microreactors (pico‐ to nanoliter volumes) optionally hosting human cells. However, one limitation is that mammalian cells within droplets are not fully accessible from ...

Studies on Drosophila hematopoiesis have thus far focused on the embryonic and larval origin of hemocytes, the fly blood cells. In this issue of Developmental Cell, Ghosh et al. (2015) identify adult hematopoietic hubs containing progenitors that can diffe ...

Rapid optimisation of a lactate biosensor design using soft probes scanning electrochemical microscopy

Hubert Girault, Andreas Stephan Lesch, Fernando Cortes Salazar

We report the mapping of biocatalytically active surfaces, particularly on an express search for optimal immobilization conditions of the enzyme lactate oxidase by means of scanning electrochemical microscopy (SECM). With this aim, soft stylus SECM probes ...

Measurement of absolute cell volume, osmotic membrane water permeability, and refractive index of transmembrane water and solute flux by digital holographic microscopy

Pierre Magistretti, Christian Depeursinge, Pierre Marquet, Pascal Jourdain, Daniel Boss

A dual-wavelength digital holographic microscope to measure absolute volume of living cells is proposed. The optical setup allows us to reconstruct two quantitative phase contrast images at two different wavelengths from a single hologram acquisition. When ...

Membrane properties revealed by spatiotemporal response to a local inhomogeneity

Anne-Florence Raphaëlle Bitbol

We study theoretically the spatiotemporal response of a lipid membrane submitted to a local chemical change of its environment, taking into account the time-dependent profile of the reagent concentration due to diffusion in the solution above the membrane. ...

Mm-size bistable zipping dielectric elastomer actuators for integrated microfluidics

Herbert Shea, Samuel Rosset, Luc Maffli

We report on a new structure of Dielectric Elastomer Actuators (DEAs) called zipping DEAs, which have a set of unique characteristics that are a good match for the requirements of electrically-powered integrated microfluidic pumping and/or valving units as ...

Spatially-Resolved Eigenmode Decomposition of Red Blood Cells Membrane Fluctuations Questions the Role of ATP in Flickering

Pierre Magistretti, Dimitri Nestor Alice Van De Ville, Christian Depeursinge, Benjamin Rappaz, Pierre Marquet, Daniel Boss, Annick Hoffmann

Red blood cells (RBCs) present unique reversible shape deformability, essential for both function and survival, resulting notably in cell membrane fluctuations (CMF). These CMF have been subject of many studies in order to obtain a better understanding of ...
