The present disclosure relates to a microfluidic device comprising: a substrate; a culture chamber (130); a loading channel (170) in fluid communication with the culture chamber; at least one auxiliar channel (170-1, 5 170-2) extending from and in fluid co ...
2023Portable impedance-sensing device for microorganism characterization in the field
A variety of biosensors have been proposed to quickly detect and measure the properties of individual microorganisms among heterogeneous populations, but challenges related to cost, portability, stability, sensitivity, and power consumption limit their app ...
NATURE PORTFOLIO2023Acoustofluidic large-scale mixing for enhanced microfluidic immunostaining for tissue diagnostics
Martinus Gijs, Diego Gabriel Dupouy, Muaz Salama Abdelmonem Draz
The usage of microfluidics for automated and fast immunoassays has gained a lot of interest in the last decades. This integration comes with certain challenges, like the reconciliation of laminar flow patterns of micro-scale systems with diffusion-limited ...
ROYAL SOC CHEMISTRY2023Particle-sorting fluidic device and methods for using thereof
Carlotta Guiducci, Gloria Porro, Kevin Keim
Device, system and method for sorting particles comprised into a fluid are disclosed that improve the current settings of deterministic lateral displacement (DLD)-based microfluidic devices, so to sort and detect small particles such as extracellular vesic ...
2022Fabrication of micrometer-sized drops as templates for particles
Drops are omnipresent in our daily life for example in the form of rain drops or as oil drops in a salad dressing. On a technological basis, drops can be used to conduct chemical or biological reactions. These drops often serve as templates to produce mate ...
EPFL2021Design and fabrication of a vigorous "cavitation-on-a-chip" device with a multiple microchannel configuration
Luis Guillermo Villanueva Torrijo, Morteza Ghorbani, Merve Zuvin, Mohammad Jafarpour, Farzad Rokhsar Talabazar
Hydrodynamic cavitation is one of the major phase change phenomena and occurs with a sudden decrease in the local static pressure within a fluid. With the emergence of microelectromechanical systems (MEMS), high-speed microfluidic devices have attracted co ...
SPRINGERNATURE2021Impedance-Based Single-Cell Pipetting
Philippe Renaud, Yann Barrandon, David Vincent Bonzon, Jean-Baptiste Bureau, Georges Muller, Nicolas Jean Bernard Beuchat, Nicolas Uffer
Many biological methods are based on single-cell isolation. In single-cell line development, the gold standard involves the dilution of cells by means of a pipet. This process is time-consuming as it is repeated over several weeks to ensure clonality. Here ...
SAGE PUBLICATIONS INC2020Positional dependence of particles and cells in microfluidic electrical impedance flow cytometry: origin, challenges and opportunities
Philippe Renaud, Jonathan Bastien Cottet
Microfluidic electrical impedance flow cytometry is now a well-known and established method for single-cell analysis. Given the richness of the information provided by impedance measurements, this non-invasive and label-free approach can be used in a wide ...
2020Dynamic response of a compressible binary fluid mixture
Binary fluids are present in a wide variety of systems at microscales, such as microfluidic devices containing drops, fluids with air bubbles trapped in them, and devices designed to mix fluids or to make two fluid substances react. Microfluidics devices a ...
2020Microfluidic-based linear-optics label-free imager
Linear optics based nanoscopy previously reached resolution beyond the diffraction limit, illuminating samples in the visible light regime while allowing light to interact with freely moving metallic nanoparticles. However, the hydrodynamics governing the ...
