On the use of polymeric additives to promote plasma separation from whole blood in open microchannels
Polymers additives in whole blood are known to modify blood physical properties. For example, Dextran molecules usually accelerate the aggregation of re-suspended RBCs in Ringer solutions. In this work, we first investigate the effect of [...]
Deterministic Lateral Displacement (DLD): Finite element modeling and experimental validation for particle trajectory and separation
Pariset E., Berthier J., Révol-Cavalier F., Pudda C., Gosselin D., Navarro F., Icard B., Agache V., CEA-LETI, FR
In biotechnology and biology, deterministic lateral displacement (DLD) arrays are used to separate particles based on their size, such as cells, bacteria, parasites and exosomes. DLD is very promising for sample preparation purposes as it [...]
3-D electrode configuration for electrochemical impedance spectroscopy of bulk solution
Abstract In this paper, a 3-D electrode configuration for electrochemical impedance spectroscopy (EIS) of a bulk solution was studied. Top- and bottom- electrode configuration, where two electrodes sandwich the sensing channel, was fabricated using the [...]
Two-Dimensional Analysis of the Enhanced Magnetic Bioseparation in Microfluidic Systems
The separation of magnetically-labeled bioparticles in a microfluidic system is dependent on the characteristics of the particles and the carrier fluid as well as the external magnetic field. To discuss the influence of these factors, [...]
Design and development of Microfluidic Platform for Water Analysis
Simple, cost- effective water analysis facilities are essential in developing countries like India [1]. Heavy metal ion contamination is one of the major causes of chemical pollution [2], like many rivers in India. In general, [...]
Low-cost screen printed and embossed LAMP micro-reactors
Gosselin D., Gougis M., Baque M., Maffini-Alvaro V., Mailley P., Bourdat A.G., Vignoud S., Navarro F., Belgacem M.N., Chaussy D., Berthier J., CEA-Grenoble, FR
Introduction: Diagnostic is probably the most important step in the fight against infectious diseases and epidemics. While it is necessary to give a treatment to diseased people, it is just as important to give the [...]
On the use of Zisman’s function for the determination of the velocity of spontaneous capillary microflows
Berthier E., Berthier J., Lee Jing, Gosselin D., Navarro F., Berthier E., Berthier J., Theberge A., CEA-LETI, FR
Capillary-based microfluidic systems are increasingly used in the fields of biotechnology, medicine, thermics, energy and space. In such systems the energy source responsible for the flow is the surface energy of the walls. Extending the [...]
Numerical Investigation Of Rigid Microparticles Dynamics: Aggregation And Clogging Phenomena In Microfluidics By Discrete Element Method (DEM) And CFD Coupling
Microfluidics has achieved a positive response in the industrial sector in the last two decades, i.e., due to its minute size plus control over all the chemical and physical properties at various flow rates (Re~1-10) [...]
CFD analysis of particle magnetophoresis in multiphase continuous-flow bioseparators
The use of magnetic particles has recently expanded for a process known as detoxification in which different toxins and microorganisms are captured from the bloodstream of septic patients. Magnetic particle-based detoxification has been successfully applied [...]
Numerical Analysis of Acoustophoretic Discrete Particle Focusing in Microchannels
Karampelas I.H., Gómez-Pastora J., Cowan M.J., Bringas E., Ortiz I., Furlani E.P., Flow Science Inc., US
Acoustophoretic particle focusing is a modern and very attractive method of removing a variety of objects from solutions in a microfluidic channel [1]. The process is inherently general and can be readily extended for multiple [...]
Two-phase spontaneous capillary microflows and the transport of capillary wagons
Berthier E., Berthier J., Brakke K., Lee Jing, Gosselin D., Navarro F., Theberge A., Berthier E., Berthier J., CEA-LETI, FR
The use of capillarity to move fluids at the microscale has been soaring lately due to new applications in medicine, biology, biotechnology, energy, thermic and space. Especially of interest are open capillary channels. These channels [...]
Interaction of a millimeter sized droplet on the powder substrates and study of capillarity in porous media flow
Droplet impact on powder materials is a ubiquitous phenomenon in nature and engineering technologies including powder-binder based 3D printing, wet granulation, spray drying, powder coating, agricultural sprays, water erosion of soil, and raindrops landing on [...]
Laser-Induced Motion of a Nanofluid in a Micro-channel
Laser-Induced Motion of a Nanofluid in a Micro-channel Tran X. Phuoc, Mehrdad Massoudi and Ping Wang National Energy Technology Laboratory, U. S. Department of Energy, P. O. Box 10940 Pittsburgh, PA 15236 * Corresponding author: [...]
Real-time bacterial capture and sorting using dielectrophoresis and electroosmosis
Fluid-Screen, Inc. presents a bacterial capture and sorting method based on dielectrophoresis (DEP) and electroosmosis (EO). These electronic phenomena have been known to influence particle motion and capture since the 1960’s, however, technology based on [...]
LIF based fluorescent immunosensor using AP-SNs and QDs for quantitation of IgG anti Toxocara canis in human serum samples
Messina G.A., Aranda P.R., Pereira S.V., Bertolino F.A., Raba J., INQUISAL, National University of San Luis, CONICET, AR
Toxocariasis, one of the most common zoonotic infection worldwide, is caused by Toxocara canis (T. canis), or less commonly, Toxocara cati [1,2]. In humans, the infection is acquired by oral route through accidental ingestion of [...]
Self-Assembled Polystyrene Nanospheres for Plasmonic Enhancement in Biosensor Applications
The field of portable, point-of care biosensing has expanded in recent years to encompass a wide range of application areas, with detection of targets accomplished by a variety of techniques. Application-specific needs of further reduced [...]
