High-throughput multiplexed fluorescence-activated droplet sorting.

Fluorescence-activated droplet sorting (FADS) is one of the most important features provided by droplet-based microfluidics. However, to date, it does not allow to compete with the high-throughput multiplexed sorting capabilities offered by flow cytometery. Here, we demonstrate the use of a dielectrophoretic-based FADS, allowing to sort up to five different droplet populations simultaneously.

Microfluidics as a Strategic Player to Decipher Single-Cell Omics?

Most cell studies are performed at a population level, relying on the assumption of a normal distribution of the function and fate of a cell among a population. However, technologies allowing single-cell analysis (SCA) have recently arisen and have led to increasing evidence of cell population heterogeneity and its importance. Tremendous amounts of new data could now be uncovered to redefine our understanding of cell omics.

High throughput single cell counting in droplet-based microfluidics.

Droplet-based microfluidics is extensively and increasingly used for high-throughput single-cell studies. However, the accuracy of the cell counting method directly impacts the robustness of such studies. We describe here a simple and precise method to accurately count a large number of adherent and non-adherent human cells as well as bacteria.

Multiplex Detection of Rare Mutations by Picoliter Droplet Based Digital PCR: Sensitivity and Specificity Considerations.

In cancer research, the accuracy of the technology used for biomarkers detection is remarkably important. In this context, digital PCR represents a highly sensitive and reproducible method that could serve as an appropriate tool for tumor mutational status analysis. In particular, droplet-based digital PCR approaches have been developed for detection of tumor-specific mutated alleles within plasmatic circulating DNA.

Parallelized ultra-high throughput microfluidic emulsifier for multiplex kinetic assays.

Droplet-based microfluidic technologies are powerful tools for applications requiring high-throughput, for example, in biochemistry or material sciences. Several systems have been proposed for the high-throughput production of monodisperse emulsions by parallelizing multiple droplet makers. However, these systems have two main limitations: (1) they allow the use of only a single disperse phase; (2) they are based on multiple layer microfabrication techniques.

[Digital PCR compartmentalization II. Contribution for the quantitative detection of circulating tumor DNA].

Genetic markers are now widely used in the clinics, particularly in cancer patient management. Indeed, these tumor markers can help in the diagnosis and prognosis of the disease, and provide valuable information for treatment orientation in the context of personalized medicine. The presence of circulating cell-free tumor DNA (cftDNA) and thus of tumor markers in the blood can be considered to partly avoid the use of solid biopsies.

Mechanical control of cell flow in multicellular spheroids.

Collective cell motion is observed in a wide range of biological processes. In tumors, physiological gradients of nutrients, growth factors, or even oxygen give rise to gradients of proliferation. We show using fluorescently labeled particles that these gradients drive a velocity field resulting in a cellular flow in multicellular spheroids.
