Fabrication and Characterization of Thermo-pneumatic Peristaltic Micropumps

Liao H-H, Liao W-C, Liao H-H, Liao W-C, Yang Y-J, National Taiwan University, TW

In recent years, the application of microelectromechanical systems (MEMS) technology on biomedical fluidic analysis has progressed rapidly. By minimizing the system, the time of analysis and reaction can be effectively shortened. Also, the quantities of [...]

Discrete Volume Controllable Microdispenser Module

Lee J., Lee S., Lee J., Lee S., Seoul National University, KR

We report a microdispenser that can meter and mix sub-nanoliter liquids in a discrete quantity. Our device is based on the structural stopping valve used in passive dispensers. A vent channel was proposed, designed for [...]

Micro bioreactor for muliwell plates with an active micro fluidic system for 3D cultivation

Weise F., Augspurger C., Klett M., Schober A., Technische Universitat Ilmenau, DE

We have designed a micro system - suitable for parallelization - to culture cells three dimensional. Our system consists of the CellChip, a body and a pneumatically driven micro pump.The aim of our system is [...]

Integrated Thermal Modulation and Deflection of Viscous Microjets with Applications to Continuous Inkjet Printing

Furlani E.P., Ng K.C., Lopez A.G., Anagnostopoulos C., Eastman Kodak, US

We present a novel CMOS/MEMS microfluidic device that enables the controlled production and redirection of streams of picoliter-sized droplets at frequency rates in the hundreds of kilohertz range. This device consists of a pressurized reservoir [...]

A Novel Parallel Flow Control (PFC) System for Syringe-Driven Nanofluidics

Liang H., Nam W.J., Fonash S.J., The Pennsylvania State University, US

In this work, we introduce the parallel flow control (PFC) configuration shown in Fig. 1 to address these key interfacing and flow control issues. PFC uses flow in a pressure-driven micro-channel, which interfaces with the [...]

Electrostatic Induced Inkjet Printing System for Micro Patterning and Drop-On-Demand Jetting Characteristics

Choi J., Kim Y., Kim Y.J., Son S.U., Kim Y., Kim Y.J., Lee S., Byun D., Ko H.S., Sungkyunkwan University, KR

Printing technology is considered to be a key technology even in the field of electronics, materials processing, and bio applications. Inkjet printing is an interesting patterning technique for electronic devices because it requires no physical [...]

Hollow Atomic Force Microscopy Probes for Nanoscale Dispensing of Liquids

Meister A., Przybylska J., Niedermann P., Santschi C., Heinzelmann H., CSEM SA, CH

The demand for specific tools intended for the deposition of small amount of material on a nanoscale at predefined location is continuously increasing. Several dispensing tools for liquid, such as ink-jet or pin-spotting heads have [...]

Generation of picoliter and nanoliter drops on-demand in a microfluidic chip

Xu J., Attinger D., Columbia University, US

In this work, we introduce the novel technique of in-chip drop-on-demand, which consists in dispensing picoliter to nanoliter drops on demand directly in the liquid-filled channels of a polymer microfluidic chip. The technique involves a [...]

Fluidic and Electrical Characterization of 3D Carbon Dielectrophoresis with Finite Element Analysis

Martinez-Duarte R., Collado-Arredondo E., Cito S., Martinez S.O., Martinez-Duarte R., Madou M., University of California Irvine, US

The following work presents the fluidic and electrical characterization of a 3D electrodes array to be used in high throughput and high efficiency Carbon Dielectrophoresis (CarbonDEP) applications such as multi-stage filters, continuous particle enrichment and [...]

Ultrasound-driven viscous streaming, modelled via momentum injection

Packer J., Attinger D., Ventikos Y., University of Oxford, UK

Mixing, particle transport, and lysis of biological cells can be performed in microfluidic chips by actuators based on the controlled motion of a gas-liquid interface. There is strong motivation to develop practical and tractable computational [...]
