Towards scalable and deterministic single cell gene expression profiling

Characterizing tissue composition at the cellular level is essential for understanding the human body in health and disease, and has been one of the frontiers in biology for centuries. Recently developed single-cell RNA-sequencing (scRNA-seq) techniques no ...

Self-Propulsion of Active Colloids via Ion Release: Theory and Experiments

Ignacio Pagonabarraga Mora

We study the self-propulsion of a charged colloidal particle that releases ionic species using theory and experiments. We relax the assumptions of thin Debye length and weak nonequilibrium effects assumed in classical phoretic models. This leads to a numbe ...

Microfluidic device performing on flow study of serial cell–cell interactions of two cell populations

Clarisse Jeanne Antonia Benoit, Philippe Renaud, George Coukos, Alexandre Harari, Thamani Dahoun, Margaux Catherine Marie Duchamp

In this study we present a novel microfluidic hydrodynamic trapping device to probe the cell–cell interaction between all cell samples of two distinct populations. We have exploited an hydrodynamic trapping method using microfluidics to immobilize a batch ...

Microfluidic platforms for high-throughput mammalian cell printing, transfection, and dosage-dependent studies

Kristina Pan Woodruff

With the advent of high-throughput and genome-wide screening initiatives, there is a need for improved methods for cell-based assays. Current approaches require expensive equipment, rely on large-scale culturing formats not suited for small or rare sample ...

Metal-Coated SU-8 Structures for High-Density 3-D Microelectrode Arrays

Carlotta Guiducci, Samuel Kilchenmann, Pietro Maoddi, Enrica Rollo

Electric fields can be effectively used to sense, manipulate, and move particles in lab-on-a-chip devices. Nevertheless, the throughput of such devices is a critical issue, which can be effectively improved by increasing the height of the microchannels. Fo ...

A Simple and Reliable PDMS and SU-8 Irreversible Bonding Method and Its Application on a Microfluidic-MEA Device for Neuroscience Research

Philippe Renaud, Arnaud Bertsch, Patrick Fraering, Marc Olivier Heuschkel, Sébastien Mosser, Yufei Ren

Polydimethylsiloxane (PDMS) and SU-8 are currently two very commonly used polymeric materials in the microfluidics field for biological applications. However; there is a pressing need to find a simple, reliable, irreversible bonding method between these tw ...

On-Chip Fabrication of Paclitaxel-Loaded Chitosan Nanoparticles for Cancer Therapeutics

Philippe Renaud, Arnaud Bertsch, Mohammad Mahdi Hasani-Sadrabadi, Jules John Vandersarl

The use of solvent-free microfluidics to fine-tune the physical and chemical properties of chitosan nanoparticles for drug delivery is demonstrated. Nanoparticle self-assembly is driven by pH changes in a water environment, which increases biocompatibility ...

Microtechnologies to Map the Fate of Single Stem Cells and their Progeny

Stefan Kobel

Since stem cells have the unique ability to produce more of themselves (i.e. to "self-renew") and to generate specialized tissue cells, they are an ideal source of cells for regenerative medicine and in vitro tissue models. In order to fully exploit this p ...
