Microporous Membrane Integrated Microfluidic System for Cell–based Assay

Hydophilic polypropylene microporous membrane for using in a membrane bioreactor system and optimization of preparation conditions by response surface methodology

In this study, the response surface methodology (RSM) based on the central composite design (CCD) was used to optimize the preparation condition of polypropylene-grafted maleic anhydride (PP-g-MA) microporous membrane by thermally-induced phase separation (TIPS) method. A mixture of dibutyl phthalate (DBP) and dioctyl phthalate (DOP) was used as diluent. The effect of polymer composition and qu...

Integrated cell manipulation system--CMOS/microfluidic hybrid.

Manipulation of biological cells using a CMOS/microfluidic hybrid system is demonstrated. The hybrid system starts with a custom-designed CMOS (complementary metal-oxide semiconductor) chip fabricated in a semiconductor foundry. A microfluidic channel is post-fabricated on top of the CMOS chip to provide biocompatible environments. The motion of individual biological cells that are tagged with ...

Integrated optical measurement system for fluorescence spectroscopy in microfluidic channels

Microfluidic Systems Integrated Microfluidic Systems**

Microfluidic systems use networks of channels thinner than a human hair to manipulate nanoliter volumes of reagents. The goal of microfluidics is challenging: to integrate, on a chip smaller than a credit card, all operations normally performed in a chemical or medical laboratory. Synthesis, purification, analysis, and diagnostics would be performed by such a “lab on a chip” rapidly, economical...

A Review of Membrane Technology for Integrated Forest Biorefinery

More recently, the concept of integrated forest biorefinery (IFBR) has received much attention as a promising solution for the struggling forest industry in North America and Europe to overcome its difficult financial period and competes globally. This new business paradigm offers a broad range of potentially attractive products, from bioenergy to value-added green organic chemicals in addition...
