Companion diagnostic test using digital microfluidic

Fouillet Y., Den Dulk R., Fuchs O., Boizot F., Menneteau M., Navarro F., CEA-LETI, FR

Companion diagnostics are an indispensable part of personalized medicine, providing information that is essential for the safe and effective use of a corresponding therapeutic drug. Such devices need to be robust, transportable and easy to [...]

A stand-alone and portable microfluidic platform for quantitative multi-step assays

Parent C., Verplanck N., L. Achard J-, Boizot F., Charles R., Fouillet Y., CEA-LETI, FR

This paper reports an automated platform for quantitative multi-step assays composed of two main components: a microfluidic chip using collapsible chambers pneumatically actuated and a portable instrument to automate the fluidic operations. To achieve a [...]

Design of Magnetic Blood Cleansing Microdevices through experimentally validated CFD modeling

Gómez-Pastora J., González-Fernández C., Karampelas I.H., Bringas E., Furlani E.P., Oriiz I., Flow Science Inc., US

Continuous flow bioseparators allow magnetic particles that are properly functionalized so that they get attached to dangerous pathogens, to be easily captured in a buffer solution. Specifically, the unique properties of magnetic particles enable their [...]

Microfluidic Test Target for Photoacoustic Imaging

Schneider P., Eadie N., Christie L., Zhan Y., Siskar T., Koh D., Xia J., Oh K.W., University at Buffalo's Sensors & MicroActuators Learning Lab (SMALL), US

Photoacoustic imaging involves the use of optics (typically a high power pulsed laser) and acoustics (ultrasonics frequency ranges >1MHz) to image a targeted object. Individually, these modalities, being optical and ultrasonic imaging, can be quantified [...]

Additive Manufacturing of Microfluidic Components via Wax Extrusion

Schneider P., Sukhotskiy V., Christie L., Siskar T., Karampelas I.H., Furlani E.P., Oh K.W., University at Buffalo's Sensors & MicroActuators Learning Lab (SMALL), US

Fused deposition modelling (FDM) has been extensively applied in the fields of rapid prototyping and 3D printing, but typically this technique has mostly been used for the fabrication of low melting point plastics. This paper [...]

A compact syringe-assisted vacuum-driven micropumping with a constant flow rate

Wang A., Koh D., Schneider P., Oh K.W., University at Buffalo, US

Abstract In this paper, a simple syringe-assisted pumping method was introduced. Compared with previous study [1], the proposed design does not require pre-designed vacuum chambers, the multiple pumps can be integrated into one device and [...]

Electric Field Assisted Placement of Carbon Nanotubes Using Sacrificial Graphene Electrodes

Engel M., Farmer D., Tirapu Azpiroz J., Seo J.-W.T., Kang J., Avouris P., Hersam M.C., Krupke R., Steiner M., IBM Research, BR

Here we detail a complete process flow to overcome the challenge of placement of carbon nanotubes on solid surfaces, limiting "bottom-up", large-scale integration in semiconductor process technology. To date most bottom up placement strategies are [...]

Strain sensing with CNT nanocomposites: static, cyclic and dynamic electromechanical material characterization.

Magnafico E., Casalotti A., Karimzadeh M., Chytanya Chinnan K., Lanzara G., University of Rome, Roma Tre, IT

Carbon Nanotube (CNT) nanocomposites are one of the most important candidates to realize innovative strain sensors for Structural Health Monitoring (SHM) applications. In this work, sensors were made of Multi-walled Carbon Nanotubes (MWNTs) embedded in [...]

Dispersion technology for CNTs with nano pre-mixer

Takatsuka T., Iida Y., THINKY corporation, JP

Carbon nanotubes (CNTs) and other strongly aggregated materials by van der Waals’ force are known for their excellent material properties with fewer amounts when they are deagglomerated and dispersed. Nano pre-mixer’s, PR-1* (THINKY, Japan), operating [...]
