Applied Systems and Synthetic Biology in Micro-Fluidic Biochips

Zeng B.J., Benjoe Institute of Systems Bioengineering, CN

The design of bio-molecular systems within cells, it is a recently achievement of synthetic biology and systems biotechnology [1]. Due to the structurity laws [2] of the synthetic biosystems theory: 1).structure integration, coordinative organization of [...]

Visual Motion Analysis of Nanoplatforms Flow under an External Magnetic Field

Nakhmani A., Etgar L., Tannenbaum A., Tannenbaum R., Lifshitz E., Tannenbaum A., Tannenbaum R., Technion – Israel Institute of Technology, IL

We use the tools of nanotechnology and develop a visual tracking algorithm for motion analysis of nanoplatforms under the influence of an external magnetic field. We have studied quantitative relationships between nanoplatform sizes, fluid flow [...]

Study of the phenomenon of meniscus deformation and ejection by pulse voltage and frequency in drop-on-demand EHD printing

Son S., An K., Kim Y.J., Choi J., Lee S., Sungkyunkwan University, KR

EHD (electrohydrodynamics) printing has recently attracted attention for micro/nano size pattern devices due to it can make very small droplet than nozzle diameter and possibility of the use of various ink such as including metal, [...]

Effect of laser processing parameters and glass type on topology of micro-channels

Ben Azouz A., Brabazon D., Vázquez M., Macka M., Dublin City University, IE

Traditional techniques to manufacture micro-fluidic devices are well established but most are limited to surface micro-fabrication. Laser micro-machining provides an alternative technique for micro-fabrication of devices. This paper presents the fabrication of 3-D micro-channel structures [...]

Analysis of prediction capability for internal micro-channels fabrication in polycarbonate and PMMA

Karazi S.M., Brabazon D., Dublin City University, IE

This paper presents a 3^3 factorial Design of Experiment (DoE) and Artificial Neural Networks (ANN) for the prediction of two characteristics of the pulsed Nd:YVO4 laser machined internal micro-channels in Polycarbonate and PMMA glass. Power, [...]

Innovative Strobe-Based Drop Analysis Equipment for Non-Contact Dispensing Systems

Kipman Y., ImageXpert Inc., US

A fully integrated machine-vision based system has been developed for visualization and measurement of drops-in-flight from non-contact dispensing tips. Unlike previously offered systems in the marketplace, this system can be used with any frequency-based jetting [...]

Novel ultra-fine hollow needles formed on Silicon membranes

Sanaee Z., Mohajerzadeh S., University of Tehran, IR

In this paper we report the realization of record-small hollow needles. The fabrication process does not need a three-dimensional lithography and uses a high precision deep vertical etching in a hydrogenation assisted ion etching unit. [...]

Optimized Surface Patterning Tools for Sub-attoliter Volume Fluid Deposition

Adams M.L., University of South Alabama, US

Micromachined cantilever-based surface patterning tools were optimized to allow submicron diameter printing of fluids on various surfaces. A detailed fluidics model was used to analyze critical variables and determine the best method for optimization. Tools [...]

Droplet actuation in PPy redox process

Tsai Y-T, Choi C-H, Yang E.H., Stevens Institute of Technology, US

A wettability switchable surface will be demonstrated to study the contact angle hysteresis of liquid droplet. Manipulation of surface wettability can be applied in the field of biomedical (cell-surface interaction) and fluids dynamics (friction reduction). [...]

Toward reliable synthesis of radiotracers for positron emission tomography in PDMS microfluidic chips: Study and optimization of the [18F] fluoride drying process

Tseng W-Y, University of California, Los Angeles, US

Positron Emission Tomography (PET) is a powerful imaging tool with high sensitivity and molecular specificity. Microfluidic systems have shown great promise for the preparation of PET tracers labeled with fluorine-18 (F-18), especially those based on [...]
