N2 - Herein we report the development of a new passive micromixer with 3-D structure based on Baker's transformation. The 3-D structure was fabricated on an oxygen-free copper block by using an ultrasonic elliptical vibration cutting method [1] and was used as a mold master. Using this master mold, we fabricated a PDMS micromixer chip. The mixing efficiency of the micromixer was evaluated by measuring the fluorescence image that results from mixing of two liquids (FITC solution and water). From these measurements, we found that the mixing efficiency at relatively high flow rate conditions is much better than that of low flow rate conditions. The mixing behavior in the microchannel was observed by a confocal fluorescence microscopy.
