• Bio-sensor using Microtubules (PI)

  • This project aims to develop a novel biosensor by using nanostructural characteristics of microtubules (MTs), which are one of cytoskeletons, because they can provide about 1600 binding sites/μm for target biomolecules. In addition, this biosensor is capable of selectively separating target biomoleculesFor fluorescently labeled biomolecules, functionalized MTs and bipolar electrodes enable separation and concentration in order. On the other hand, for label free biomolecules, functionalized MTs with target biomolecules pass over a nanowire so that the momentary conductance reduction of a nanowire causes I/V variation. Using these biosensing mechanisms, an ultra-sensitive (< femtomolar) nano biosensor will be developed. from a complex analyte by using the electrokinetic characteristics of MTs.

• Experimental and Numerical Analysis and Microfluidic Application of Anomalous Ion Transport and Electrokinetic Fluid Flows Induced by Surface-patterned Nanoporous Materials (PI)

  • This project aims to understand anomalous ion transport and non-linear electrokinetic fluid flow phenomena through microfabricated nanoporous membranes surface-patterned on microchannels using various ion-selective materials. Both numerical and experimental approaches will be focused on to analyze ion concentration and polarization (ICP) and 2nd kind of electroosmosis flow phenomena to develop elaborately controllable ion-/fluid mixers, ion-/fluid pumpers, and ion-/fluid valves. These elementary components and fluid control mechanisms will be integrated into a novel, actively controllable, 2D-pixelated pH concentration generator system that has high potential in micro total analysis systems.

  • Current techniques using bacterial strains to produce butanol have a limit of about 20 g/L, with typical results of about 13 g/L. Furthermore, many researchers want to use plant hydrolysates for fermentative purposes since they are a renewable source of sugars. However, hydrolysis of lignin results in numerous phenolic acids being produced, which are toxic to the bacteria. To answer both of these issues, this study will use microfluidics and toxicogenomics to develop novel reactors and study the effects of the hydrolysate compounds on several bacterial strains, respectively. Furthermore, genetically-modified strains will be constructed to provide enhanced butanol yields and productivities. This work is funded by National Research Foundation for 6 (2+2+2) years from 2009/09/30.
