Droplet Dispensing from Open to Close Digital Microfluidics

Rezaei Nejad H., University of British Columbia, CA

There are two types of DMF platforms: open and closed systems. Each platform has its own advantages. For instance, it is easier to access the droplet in the open systems; whereas, the closed system limits [...]

Open-Surface Microfluidics

Berthier J., Brakke K.A., Furlani E.P., Karampelas I.H., Delapierre G., CEA-LETI, FR

The developments of open-surface microfluidics (OSM) for biotechnology are recent, and motivated by the development of point-of-care (POC) and home-care systems. The advantages of capillary systems are (1) low cost due to easy and fast [...]

Numerical Analysis of Coupled Particle-Fluid Transport and Free-Flow Magnetic Sorting in Microfluidic Systems

Liu C., Xue X., Furlani E.P., University at Buffalo, US

Magnetic beads are increasingly used in microfluidic systems to selectively separate and sort biomaterial from a specimen for a broad range of biomedical and clinical diagnostic applications. Most theoretical studies of such systems have been [...]

Field-directed and Template-assisted Magnetic Nanoparticle Self-assembly

Xue X., Furlani E.P., SUNY at Buffalo, US

The interest in field-directed assembly of colloidal magnetic nanoparticles has grown steadily in recent years due to a proliferation of applications including targeted drug therapy, biomedical imaging, among others. Such self-assembly holds promise as a [...]

Cell Detection and Discrimination by a Microfluidic-Integrated Broadband Microchamber

Denzi A., Apollonio F., Liberti M., Caterina M., Ning Y., Multari C., Palego C., Cheng X., Hwang J.C.M., Lehigh University, US

In the last years, the development of broadband microwave sensors for cell detection has become a great challenge. In this work, a broadband microchamber integrated with microfluidics is used for cell detection in the GHz [...]

On the velocity of spontaneous capillary flows in confined and open microchannels

Berthier J., Villard N., Pudda C., Boizot F., Nonglaton G., Costa G., Fontelaye C., Delapierre G., CEA-LETI, FR

In biotechnology and biology, conventional microfluidic systems using fluids moved by pumps, syringe or electric means are not the best solutions when portability and low-cost are an issue. Capillary-based systems fulfill the requirements for POC [...]

A novel Planetary Motion of Ferrofluid Drops in a Rotating Magnetic Field

Chen C-Y, National Chiao Tung University, TW

Driven by an external rotating field, a novel phenomenon of planetary-like double rotations, such as a local self-spin of individual drops and the global revolution of the drop array, is uncovered in arrayed ferrofluid drops. [...]

Introducing a Digital Micropump for Driving a Droplet in a Microfluidic Channel

Rezaei Nejad H., University of British Columbia, CA

This paper presents a novel pumping technique which is compatible with both digital and continuous microfluidic platforms. In essence, a target droplet (referred to as the pumped droplet) is pumped by actuating the secondary droplet [...]

TCAD Thermal Analysis of Gate Workfunction Engineered Recessed Channel MOSFET

Arora G., Monika M., Chaujar R., Delhi Technological University, IN

This paper discusses the thermal analysis of Gate Electrode Workfunction Engineered Recessed Channel (GEWE-RC) MOSFET involving an RC and GEWE design integrated onto a conventional MOSFET. Furthermore, it focuses on the comparative study of conventional [...]
