System for Measuring Drop Volume and Consistency in Lab-on-Chip Applications

Kipman Y., Mehta P., ImageXpert Inc., US

A machine vision based system has been developed for measuring in-channel characteristics of droplets for lab-on-chip microfluidic applications. The small, fully integrated system can be used in R&D and in production and combines a high-powered [...]

Modularity in the Design and Volume Production of Microfluidic Devices

Podczerviensky J., Levine L., ALine, Inc., US

Robust fabrication of functional components in microfluidic devices will drive down their cost and improve their performance. We have developed a modular and readily customized approach for routine and volume production of complex microfluidic devices [...]

Facile Fabrication of an Enzyme Microreactor Using Magnetic Microbeads

Liu X., Lo R.C., Gomez F.A., California State University Long Beach, US

In this paper, we present a simple method to fabricate an enzyme microreactor using soft lithography and magnetic microbeads. For proof of concept, we performed an enzymatic reaction by flowing non-fluorescent resazurin through diaphorase (DI) [...]

Polymer Simulation in a Microfluidic Entropic Trap

Kallemov B., Trebotich D., Miller G.H., Lawrence Berkeley Natinal Laboratory, US

We have developed a novel algorithm for the simulation of polymer-laden flows in microfluidic devices. Our algorithm is based on a hybridization of high order accurate continuum and particle methods. The continuum method provides the [...]

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 [...]

Novel Parameters for Rapid Blood Separation on a Centrifugal Platform

Gorkin R., Kim T-H., Madou M., Cho Y-K, University of California Irvine, US

Centrifugal microfluidic platforms are emerging as strong candidates for advanced integrated clinical diagnostics for such applications as automated immunoassay processing and nucleic acid analysis, however several implementation challenges limit their widespread use today. Purification of [...]
