Acoustofluidic 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 CHEMISTRY2023Efficient AC electrothermal flow (ACET) on-chip for enhanced immunoassays
Martinus Gijs, Diego Gabriel Dupouy, Muaz Salama Abdelmonem Draz
Biochemical reaction rates in microfluidic systems are known to be limited by the diffusional transport of reagents, leading often to lowered sensitivity and/or longer detection times in immunoassays. Several methods, including electrically powering electr ...
ROYAL SOC CHEMISTRY2023Development of next-generation microfluidic systems for enhanced, faster, and cost-effective immunoassays for tissue diagnostics - Ac electrothermal flow & Acoustofluidics
The application of microfluidics in the field of surface-based assays and more specifically, the spatial molecular profiling of tumor tissues has gained a lot of interest, especially with the increased interest in personalized medicine and targeted therapy ...
EPFL2023Analytic modelling of passive microfluidic mixers
Jean-Michel Sallese, Christophe Lallement
This paper deals with a new analytical model for microfluidic passive mixers. Two common approaches already exist for such a purpose. On the one hand, the resolution of the advection-diffusion-reaction equation (ADRE) is the first one and the closest to ph ...
AMER INST MATHEMATICAL SCIENCES-AIMS2022Three-dimensional electrodes for dielectrophoretic applications
This thesis reports the use of metal-coated three-dimensional SU-8 electrodes for dielectrophoretic bio sensing and particle manipulation applications. Placing free standing three-dimensional electrodes in microfluidic channels, electric fields can be appl ...
EPFL2020Interaction and breakup of droplet pairs in a microchannel Y-junction
We combine theory, numerical simulation, and experiments to investigate the breakup of two identical droplets entering a Y-junction with controlled spatial offset by which the second droplet trails the first. Based on fully resolved 3D simulations, we desc ...
AMER PHYSICAL SOC2020Rational design of a high-throughput droplet sorter
Tobias Schneider, Simon Sebastian Schütz
The high-throughput selection of individual droplets is an essential function in droplet-based microfluidics. Fluorescence-activated droplet sorting is achieved using electric fields triggered at rates up to 30 kHz, providing the ultra-high throughput rele ...
2019Programmable Multistable Mechanisms for Safe Surgical Puncturing
Simon Nessim Henein, Charles Baur, Andrea Lovera, Ilan Vardi, Mohamed Gamal Abdelrahman Ahmed Zanaty, David Lambelet, Thomas Jean Julien Fussinger, Arno Rogg
We present novel medical devices for safe surgical puncturing, in particular a cannula for the treatment of retinal vein occlusion (RVO). This passive mechanical device has an adjustable stroke and exerts a puncturing force independent of operator applied ...
ASME2019Pattern formation in thin liquid films: from coating-flow instabilities to microfluidic droplets
Gioele Mariano Nicolò Balestra
Nature and technical applications abound with thin viscous flows, ranging from the lava flow on volcanoes to the lubricating layer around confined bubbles in the microchannels of Lab-on-a-Chip devices. Countless are the examples where coating flows arise i ...
EPFL2018Distinct transition in flow statistics and vortex dynamics between low- and high-extent turbulent drag reduction in polymer fluids
Flexible polymer additives are known to reduce the energy dissipation and friction drag in turbulent flows. As the fluid elasticity increases, the flow undergoes several stages of transitions. Much attention in the area has been focused on the onset of dra ...
