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 [...]

First-Order-Reversal-Curve Analysis of Nanoscale Magnetic Materials

Dodrill B.C., Spinu L., Lake Shore Cryotronics, US

Magnetic nanowires, nanodots and nanoparticles are an important class of nanostructured magnetic materials. These structures are ideal candidates for important technological applications in spintronics, high density recording media, microwave electronics, permanent magnets, and for medical [...]

Converting Dimensions: A Facile and High-Yield Route for Getting Sub-100 nm Silicon Nanowires

Lee S-H., Yonsei University, KR

For synthesizing uniform sub-100-nm Si nanowires (NWs), we introduce a metal-assisted chemical etching (MCE)-based facile and high-yield route, employing simple thermal annealing and vacuum deposition processes. Under rapid thermal annealing, an ultrathin Ag film on [...]

A New Biocomposite Electrode Sensor for the Detection of Oxidative Reactions

Assan D., Gao X., Lai J.C.K., Leung S.W., Idaho State University, US

Hemoglobin has a very strong affinity with oxygen and thus is a good catalyst to carry oxygen for many oxidation reactions. Many researchers have explored this property of hemoglobin to develop sensors for the detection [...]
