Analysis of Stem Cell Culture Performance in a Microcarrier Bioreactor System

Ponnuru K., Wu J., Ashok P., Tzanakakis E.S., Furlani E.P., SUNY-Buffalo, US

Human pluripotent stem cells (hPSCs) are capable of differentiating into all somatic cell types and hold great potential for future clinical applications. Recent studies on cell culture in stirred tank bioreactors indicate that mechanical forces [...]

Droplet actuation on a digital microfluidic chip using a 5 volt battery

Rezaei Nejad H., University of British Columbia, CA

This paper presents a circuit using a 5-volt DC battery to actuate droplets on a DMF chip. The output of the circuit is a controllable high voltage, high frequency AC signal which can actuate a [...]

Electrowetting on screen printed paper based substrate

Yafia M., Najjaran H., University of British Columbia, CA

In this work, electrowetting on dielectric (EWOD) is performed on a paper based substrate. Electrode patterns are fabricated on a paper substrate using screen printing. Conventional photolithography fabrication techniques are replaced by screen printing conductive [...]

On-line production of polyelectrolyte coating on monodisperse alginate beads in an integrated microfluidic cartridge

Laffite G., Forvi E., Hadji C., Authesserre C., Alessio M., Costa G., Boizot F., Rivera F., CEA-LETI, FR

Continuous flow microfluidic devices have appeared to be a promising technology to automatise Polyelectrolytes multilayers (PEMs) coating on microbeads with repeatable and reliable results. However, no microfluidic devices have demonstrated PEMs coating on hydrogel beads [...]

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 [...]
