| Research Abstract |
The velocity profile of dilute polymer solutions and a distilled water near the wall surface in a microchannel was clarified using a particle tracking velocimetry technique combined with evanescent wave illumination. The results obtained for the velocity profile of a distilled water using fluorescent particles with a diameter of 20 nm was found that the resolution of the velocity profile near the wall surface was drastically improved from the conventional result. On the other hand, the velocity profile of dilute polymer solutions increased significantly compared with that of distilled water, and the gradient of the velocity profile increases with the increase of the molecular weight.
