| Outline of Final Research Achievements |
Fluorescent marking of polymers solved in fluids was conducted to evaluate the polymer conditions in fluids such as molecular weight, concentration and orientation. Further, to measure the same polymer characteristics, dielectrophoretic spectroscopy of the polymer solution was performed using parallel plate type electrodes designed for stationary fluids and micro-electrodes attached to the top and bottom walls of the microchannel. In the fluorescent labeling case, the single polymer molecule was visualized reasonably, however, there was some difficulties in measuring their distributions in fluid flows. We are now trying to apply HPam to solve this problem. On the other hand, the polymer characteristics could be measured based on the frequency the dielectric relaxation occurs. Still, measurement in microchannel flows incurs noticeable noise and we our now improving the experimental apparatus.
